Histochemical localization of immunoreactive substances using labeled antibodies as reagents.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.

The original member of the family of endothelial cell growth factors referred to as VASCULAR ENDOTHELIAL GROWTH FACTORS. Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as "tumor angiogenesis factor" and "vascular permeability factor". Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating VASODILATION via NITRIC OXIDE-dependent pathways. Alternative splicing of the mRNA for vascular endothelial growth factor A results in several isoforms of the protein being produced.

Tumors or cancer of the STOMACH.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Level of retinoblastoma protein expression correlates with p16 (MTS-1/INK4A/CDKN2) status in bladder cancer. (1/66693)Recent studies have shown that patients whose bladder cancer exhibit overexpression of RB protein as measured by immunohistochemical analysis do equally poorly as those with loss of RB function. We hypothesized that loss of p16 protein function could be related to RB overexpression, since p16 can induce transcriptional downregulation of RB and its loss may lead to aberrant RB regulation. Conversely, loss of RB function has been associated with high p16 protein expression in several other tumor types. In the present study RB negative bladder tumors also exhibited strong nuclear p16 staining while each tumor with strong, homogeneous RB nuclear staining were p16 negative, supporting our hypothesis. To expand on these immunohistochemical studies additional cases were selected in which the status of the p16 encoding gene had been determined at the molecular level. Absent p16 and high RB protein expression was found in the tumors having loss of heterozygosity within 9p21 and a structural change (mutation or deletion) of the remaining p16 encoding gene allele, confirming the staining results. These results strongly support the hypothesis that the RB nuclear overexpression recently associated with poor prognosis in bladder cancer is also associated with loss of p16 function and implies that loss of p16 function could be equally deleterious as RB loss in bladder and likely other cancers.

Decreased expression of the pro-apoptotic protein Par-4 in renal cell carcinoma. (2/66693)Par-4 is a widely expressed leucine zipper protein that confers sensitization to apoptosis induced by exogenous insults. Because the expression of genes that promote apoptosis may be down-regulated during tumorigenesis, we sought to examine the expression of Par-4 in human tumors. We present here evidence that Par-4 protein levels were severely decreased in human renal cell carcinoma specimens relative to normal tubular cells. Replenishment of Par-4 protein levels in renal cell carcinoma cell lines conferred sensitivity to apoptosis. Because apoptosis may serve as a defense mechanism against malignant transformation or progression, decreased expression of Par-4 may contribute to the pathophysiology of renal cell carcinoma.

Expression of Bcl-2 protein is decreased in colorectal adenocarcinomas with microsatellite instability. (3/66693)Bcl-2 is known to inhibit apoptosis and is thought to play a role in colorectal tumour development. Studies of the promoter region of bcl-2 have indicated the presence of a p53 responsive element which downregulates bcl-2 expression. Since p53 is commonly mutated in colorectal cancers, but rarely in those tumours showing microsatellite instability (MSI), the aim of this study was to examine the relationship of bcl-2 protein expression to MSI, as well as to other clinicopathological and molecular variables, in colorectal adenocarcinomas. Expression of bcl-2 was analysed by immunohistochemistry in 71 colorectal cancers which had been previously assigned to three classes depending upon their levels of MSI. MSI-high tumours demonstrated instability in three or more of six microsatellite markers tested, MSI-low tumours in one or two of six, and MSI-null in none of six. Bcl-2 expression in tumours was quantified independently by two pathologists and assigned to one of five categories, with respect to the number of cells which showed positive staining: 0, up to 5%; 1, 6-25%; 2, 26-50%; 3, 51-75%; and 4, > or =76%. Bcl-2 negative tumours were defined as those with a score of 0. Bcl-2 protein expression was tested for association with clinicopathological stage, differentiation level, tumour site, age, sex, survival, evidence of p53 inactivation and MSI level. A significant association was found between bcl-2 expression and patient survival (P = 0.012, Gehan Wilcoxon test). Further, a significant reciprocal relationship was found between bcl-2 expression and the presence of MSI (P = 0.012, Wilcoxon rank sum test). We conclude that bcl-2 expressing colorectal cancers are more likely to be MSI-null, and to be associated with improved patient survival. (+info)
Immune responses to all ErbB family receptors detectable in serum of cancer patients. (4/66693)Employing NIH3T3 transfectants with individual human ErbB receptor coding sequences as recombinant antigen sources, we detected by immunoblot analysis specific immunoreactivity against all four ErbB receptors among 13 of 41 sera obtained from patients with different types of epithelial malignancies. Overall, serum positivity was most frequently directed against ErbB2 followed by EGFR, ErbB3 and ErbB4. Specificity patterns comprised tumor patients with unique serum reactivity against ErbB2 or ErbB4. Moreover, approximately half of the positive sera exhibited concomitant reactivity with multiple ErbB receptors including EGFR and ErbB2, EGFR and ErbB4, ErbB2 and ErbB3 or EGFR, ErbB2 and ErbB3. Serum reactivity was confirmed for the respective ErbB receptors expressed by human tumor cells and corroborated on receptor-specific immunoprecipitates. Positive sera contained ErbB-specific antibodies of the IgG isotype. Representative immunohistochemical analysis of tumor tissues suggested overexpression of ErbB receptors for which serum antibodies were detectable in five of six patients. These findings implicate multiple ErbB receptors including ErbB3 and ErbB4 in addition to EGFR and ErbB2 in primary human cancer. Heterogeneity of natural ErbB-specific responses in cancer patients warrants their evaluation in light of immunotherapeutic approaches targeting these receptors. (+info)
Detailed methylation analysis of the glutathione S-transferase pi (GSTP1) gene in prostate cancer. (5/66693)Glutathione-S-Transferases (GSTs) comprise a family of isoenzymes that provide protection to mammalian cells against electrophilic metabolites of carcinogens and reactive oxygen species. Previous studies have shown that the CpG-rich promoter region of the pi-class gene GSTP1 is methylated at single restriction sites in the majority of prostate cancers. In order to understand the nature of abnormal methylation of the GSTP1 gene in prostate cancer we undertook a detailed analysis of methylation at 131 CpG sites spanning the promoter and body of the gene. Our results show that DNA methylation is not confined to specific CpG sites in the promoter region of the GSTP1 gene but is extensive throughout the CpG island in prostate cancer cells. Furthermore we found that both alleles are abnormally methylated in this region. In normal prostate tissue, the entire CpG island was unmethylated, but extensive methylation was found outside the island in the body of the gene. Loss of GSTP1 expression correlated with DNA methylation of the CpG island in both prostate cancer cell lines and cancer tissues whereas methylation outside the CpG island in normal prostate tissue appeared to have no effect on gene expression.

The disulfide-bonded loop of chromogranin B mediates membrane binding and directs sorting from the trans-Golgi network to secretory granules. (6/66693)The disulfide-bonded loop of chromogranin B (CgB), a regulated secretory protein with widespread distribution in neuroendocrine cells, is known to be essential for the sorting of CgB from the trans-Golgi network (TGN) to immature secretory granules. Here we show that this loop, when fused to the constitutively secreted protein alpha1-antitrypsin (AT), is sufficient to direct the fusion protein to secretory granules. Importantly, the sorting efficiency of the AT reporter protein bearing two loops (E2/3-AT-E2/3) is much higher compared with that of AT with a single disulfide-bonded loop. In contrast to endogenous CgB, E2/3-AT-E2/3 does not undergo Ca2+/pH-dependent aggregation in the TGN. Furthermore, the disulfide-bonded loop of CgB mediates membrane binding in the TGN and does so with 5-fold higher efficiency if two loops are present on the reporter protein. The latter finding supports the concept that under physiological conditions, aggregates of CgB are the sorted units of cargo which have multiple loops on their surface leading to high membrane binding and sorting efficiency of CgB in the TGN.

A cytomegalovirus glycoprotein re-routes MHC class I complexes to lysosomes for degradation. (7/66693)Mouse cytomegalovirus (MCMV) early gene expression interferes with the major histocompatibility complex class I (MHC class I) pathway of antigen presentation. Here we identify a 48 kDa type I transmembrane glycoprotein encoded by the MCMV early gene m06, which tightly binds to properly folded beta2-microglobulin (beta2m)-associated MHC class I molecules in the endoplasmic reticulum (ER). This association is mediated by the lumenal/transmembrane part of the protein. gp48-MHC class I complexes are transported out of the ER, pass the Golgi, but instead of being expressed on the cell surface, they are redirected to the endocytic route and rapidly degraded in a Lamp-1(+) compartment. As a result, m06-expressing cells are impaired in presenting antigenic peptides to CD8(+) T cells. The cytoplasmic tail of gp48 contains two di-leucine motifs. Mutation of the membrane-proximal di-leucine motif of gp48 restored surface expression of MHC class I, while mutation of the distal one had no effect. The results establish a novel viral mechanism for downregulation of MHC class I molecules by directly binding surface-destined MHC complexes and exploiting the cellular di-leucine sorting machinery for lysosomal degradation.

Expression of extracellular matrix proteins in cervical squamous cell carcinoma--a clinicopathological study. (8/66693)AIM: To evaluate the intracellular and peritumoral expression of matrix proteins in squamous cell carcinoma of the uterine cervix using immunohistochemistry. METHODS: 71 squamous cell carcinomas and 10 controls were stained for laminin, fibronectin, and collagen IV. Cytoplasmic staining in tumour cells and peritumoral deposition of matrix proteins were evaluated. The association between staining results and patient age, tumour stage, histological grade, and survival was studied. RESULTS: Positive cytoplasmic staining for laminin, fibronectin, and collagen IV was observed in 17 (23.9%), 27 (38%), and 10 (14.1%) cases, respectively. Staining for laminin was most pronounced in the invasive front of tumour islands, while for fibronectin and collagen IV it appeared to be diffuse. Peritumoral staining for laminin and collagen IV was detected in 12 cases (16.9%). Early stage (Ia1-Ia2) tumours were uniformly negative for all three proteins. Cytoplasmic staining for laminin correlated with positive staining for fibronectin and collagen IV, and with the presence of a peritumoral deposition of collagen IV and laminin. There was no correlation with any of the three markers between staining results and patient age, stage, grade, or survival. CONCLUSIONS: Expression of extracellular matrix proteins in some cervical squamous cell carcinomas might reflect the enhanced ability of these tumours to modify the peritumoral stroma. This ability seems to be absent in early stage tumours. The correlation between intracytoplasmic and peritumoral expression of matrix proteins supports the evidence of their synthesis by tumour cells. However, this property did not correlate with disease outcome in this study. (+info)

A methodology to identify consensus classes from clustering algorithms applied to immunohistochemical data from breast cancer...
Single clustering methods have often been used to elucidate clusters in high dimensional medical data, even though reliance on a single algorithm is known to be problematic. In this paper, we present a methodology to determine a set of core classes by using a range of techniques to reach consensus across several different clustering algorithms, and to ascertain the key characteristics of these classes. We apply the methodology to immunohistochemical data from breast cancer patients. In doing so, we identify six core classes, of which several may be novel sub-groups not previously emphasised in literature.. ...

PSCO Case of the Month September 2008
The diagnosis of SPT is made based on the clinical presentation, location of tumor, histological findings, and immunohistochemical staining. SPTs express positive immunohistochemical staining for vimentin, CD56, alpha-1-antitrypsin and neuron-specific enolase. Epithelial markers (keratins) may be focal or weakly positive. Synaptophysin is commonly positive in SPTs; however, chromogranin is usually negative. Immunohistochemical staining for Amylase/Lipase/Trypsin are negative, as well as those for pancreatic hormones. There may be positive immunohistochemical staining for CD10, Beta- catenin, CD117 (c-kit), Progesterone receptor, and the beta form of estrogen receptor. SPTs are considered to be tumors of low malignant potential and more than 80% of SPTs are cured by surgical resection. However, metastases may be seen in a small percentage of patients. When metastasis occurs, it is usually to the liver or peritoneum. Patient follow-up: The patient underwent a brain biopsy. Histologic examination ...

Rev. perú. med. exp. salud publica [online]. 2017, vol.34, n.3, pp.472-477. ISSN 1726-4634. http://dx.doi.org/10.17843/rpmesp.2017.343.2530.. The objective of this study was to determine the clinical and prognostic characteristics of breast carcinomas according to the molecular subtype using immunohistochemical markers. The study included 280 women with unilateral breast cancer enrolled from 2009 to 2012. The carcinomas were classified into four subtypes based on immunohistochemical findings: luminal A, luminal B, HER2, and triple negative. The Kaplan-Meier test was used to determine the effect of histological type and molecular subtype on overall survival. Our results indicated that the most common breast carcinoma subtype was luminal A (105 cases, 37.5%), followed by luminal B (88 cases, 31.4%), HER2 (46 cases, 16.4%), and triple ...
Microscopic Description -- Case 252
The tumor cells were arranged in organoid clusters or sheets and composed of round to polygonal cells with central round nucleus, abundant eosinophilic or clear cytoplasm and distinct cell membrane (IMAGES 1, 2). Myxoid matrix was also present between the tumor cells (IMAGE 3). The tumor had increased cellularity with nuclear pleomorphism and significant mitotic activity (IMAGES 4, 5). Immunohistochemical stains showed an unusual pattern of staining for CD117 (c-kit) (IMAGE 6). Instead of cytoplasmic staining as typically seen in GIST, there was predominantly nuclear staining. CD34 (IMAGE 7), smooth muscle specific actin (IMAGE 8) and S-100 (IMAGE 9) were immunostain negative. Atypical staining for CD117 and absence of positive immunohistochemical staining for CD34 in the present tumor tissue prevent a definitive diagnosis of GIST at this time. Loss of positive staining for these characteristic GIST markers could be consistent with tumor dedifferentiation over time associated with recurrence. ...
Patent US4469098 - Apparatus for and method of utilizing energy to excise pathological tissue - Google Patents
Pathological tissue is excised with a beam from a laser that is coupled through a flexible, optical waveguide to a collimator that reduces the beam cross-sectional area by variable, controlled amounts. A transparent bore or a graphite cannule couples the beam exiting the collimator to the tissue to vaporize same. An electrically responsive deflector gyrates the reduced cross-sectional area beam about a bore sight axis aligned with the cannula bore so that the excised tissue has a frusto-conical volume. To excise different, displaced tissue regions, a position servo system moves the cannula so the bore sight axis moves in a plane at right angles to a plane on the exterior surface containing the pathological tissue.

The 116 DLBCL analyzed in our study were diagnosed according to the histopathological and immunohistochemical characteristics described in the WHO classification and additionally according to novel gene expression features recently defined by our group.10. Forty-three of our 116 cases of DLBCL had a genomic gain of BCL2 and MALT1 and one case revealed an amplification of MALT1 together with a normal BCL2 gene status (together 38%), while 72 cases (62%) had normal copy numbers of the BCL2 and MALT1 genes not considering changes in ploidy. Interestingly, gain of the BCL2 gene was invariably associated with gain of the MALT1 gene in our series. Moreover, the presence of a 18q21/MALT1 gain correlated with upregulation of genes located on 18q including MALT1 at the RNA level, independently of the ABC or GCB gene expression signature, and was strongly associated with over-expression of BCL2 protein. We found a significant accumulation of cases with a 18q21/MALT1 gain among those with an ABC signature ...

CD24 shows early upregulation and nuclear expression but is not a prognostic marker in colorectal cancer | Journal of Clinical...
Background and aims: The putative stem cell marker CD24 is a small, heavily glycosylated, cell surface molecule which was originally associated with tumour metastasis. Recently it has been reported to be upregulated and of prognostic importance in colorectal tumours. The study aims to study the prognostic value of CD24 in a large series of colorectal cancer (CRC).. Methods: CD24 protein expression was examined by immunohistochemistry. A total of 10 whole tissue sections (WTS) of adenoma and 345 CRCs arranged as tissue microarrays (TMAs) were evaluated. For comparison with non-neoplastic tissue, 10 WTS containing tumour with associated non-neoplastic tissue were also studied.. Results: None of the samples of normal tissue (adjacent to tumour) showed CD24 expression. In the tumours, CD24 expression was seen on the luminal surface of the cells, within the cytoplasm and, unexpectedly, also within the nucleus. Positive immunostaining was seen in 9/10 (90%) adenomas and 313/345 (91%) of CRCs. Weak ...

Immunohistochemistry | National Diagnostics
Antibodies can be generated by injecting animals with antigens, and then collecting serum after the immune response has taken place. If the antibodies are labeled with an easily detectable molecule (a fluorescent dye, an enzyme, etc.), they become powerful detection reagents for the antigen. This system has been exploited to generate exceptionally specific and sensitive stains which are used in histology as well as other disciplines.. Immunohistochemistry/cytology is the use of antibodies in light microscopy and EM. The basic process depends upon selecting an antibody sufficiently specific to bind an antigen in situ. The antibody/antigen conjugate is then identified using a variety of signal generating molecules triggered either by the antibody/antigen interaction or by secondary processes. The signal generators can be precipitating dyes, fluorescent molecules or electron dense (ultrastructural tag) materials for electron microscopy (EM).. The first report of an immunohistochemistry technique ...
Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype with high recurrences and mortality rate, for which no therapies besides chemotherapy are available to date. Lacking specific markers for an effective targeted therapy, TNBCs continue to represent the most important challenge for clinical oncologists. Here, we investigated the expression of CDCP1, a transmembrane non-catalytic receptor reportedly associated with poor prognosis in some solid tumors (e.g., lung and pancreatic cancer), and its association with tumor aggressiveness in a cohort of 115 human TNBC primary specimens obtained from women surgically treated in our Institute from the beginning of 2002 to the end of 2006 and selected based on immunohistochemical (IHC) criteria (,1% cell positivity for estrogen receptor, progesterone receptor and HER2 expression classified as 0 or 1+). CDCP1 was overexpressed in 56.5% of human primary TNBCs. FISH analysis of 75 TNBCs for which material was available delineated four ...
CD24 Expression Is a New Prognostic Marker in Breast Cancer | Clinical Cancer Research
CD24 has been described in B-cell development and B-cell neoplasia, in the developing pancreas and brain, and in regenerating muscle, keratinocytes, renal tubules, and a large variety of malignant tumors (12 , 13 , 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30 , 32, 33, 34) . In this immunohistochemistry-based study we describe the expression of CD24 protein in breast cancer. Basically, we can confirm the findings of Fogel et al. (31) , who were the first to describe CD24 expression of breast cancer in an immunohistochemistry study based on frozen sections. They reported an apical membranous CD24 immunoreactivity in benign ducts and an additional cytoplasmic staining in invasive carcinomas, and described CD24 expression as a marker of breast cancer. We used a commercially available monoclonal CD24 antibody that is applicable to paraffinized tumor tissue and, thus, made a comprehensive analysis of clinically characterized archive material possible. The specificity of the antibody was ...

The effects of proteasomal inhibition on synaptic proteostasis | The EMBO Journal
A common method for studying the involvement of catabolic pathways in the degradation of particular proteins is to pharmacologically inhibit the pathways, and examine-by Western blots or quantitative immunohistochemistry, for example-how these manipulations affect total quantities of the proteins in question. Unfortunately, these methods are incapable of separating the effects of such inhibitors on protein degradation from effects on protein synthesis. These processes are more readily discernible in pulse‐chase experiments based on radioactive amino acids; this approach, however, is not free from confounds either: On the one hand, the slow turnover rates of synaptic proteins require relatively long labeling periods. On the other, labeling is typically associated with substantial (ten‐ to hundredfold) reductions in (labeled) amino acid concentrations, raising the risk of inducing macroautophagy (see, e.g. Sutter et al, 2013). In contrast, the methods used here do not suffer from either of ...

Histological Differentiation Grade Predicted by Ultrasound Backscatterer Imaging - Full Text View - ClinicalTrials.gov
Histological grade of hepatocellular carcinoma (HCC) is an important prognostic factor affecting patient survival. It has been divided into four grades from I to IV on the basis of histological differentiation. Grade I is the best differentiated consisting of small tumor cells arranged in thin trabeculae. Cells with higher grade are larger and less differentiated with hyperchromatic nuclei and loss of trabecular pattern.. Ultrasound is an imaging modality frequently used to evaluate liver tumors because of its convenience, real-time, less expensive and no radiation exposure. However, ultrasonographic evaluation by conventional B-mode image is semi quantitative and subjective. It still cannot replace liver biopsy for the evaluation of HCC.. This study is aimed to quantify the image characters of B-mode image and the scatterer properties using Nakagami distribution. Nakagami parameter is a general model to describe the distribution of scatterers. Therefore, the investigators hypothesized that ...

ABT-263 | Small molecule inhibitors of HCV replication
Background Fibrinogen-related proteins with lectin activity are believed to be part of the tick innate immune system. the FRePs immunostaining pattern. In D. marginatus haemolymph, anti-DMF1 serum stained the 36 kDa protein under reducing conditions. After ABT-263 deglycosylation with N-glycosidase F (cleaves off the whole N-glycan except for structures containing core (1,3)-bound fucose), reactive protein bands with molecular weights of 30, 31, 33, 34, and 36 kDa appeared (Figure ?(Figure3A).3A). The enduring reaction of the 36 kDa band suggests incomplete deglycosylation reaction. The anti-DMF1 serum detected also the 79/80 kDa proteins, which under reducing conditions migrated as three protein bands with molecular weights of 58, 60, and ABT-263 66 kDa suggesting the presence of non-covalently bound subunits. The molecular weights of these three bands decreased after N-glycosidase ABT-263 F treatment and they were observed at 54, 58, and 63 kDa (Figure ?(Figure3A).3A). Same results with lower ...

Positive immunostaining in negative control - Immunology and Histology
Hi. Ive been working with Vectastain Elite ABC kit for a month. First, I didnt get any signal in a positive human sample. This sample must to show some signal but my negative is very clean (beautiful) with 4 minutes of staining. So I decided test the kit with a positive control. Im using rat (a know sample) as my positive and the same sample as negative control without primary antibody. I suppose see signal only in my positive control but I got signal in both.
