In the past two decades, the biological and medical fields have seen great advances in the development of biosensors and biochips capable of characterizing and quantifying biomolecules. To understand the important relationship between the biosensor and nano structure we introduce this proposal to fabricate and characterize the nanogap using size reduction technique for ss-DNA immobilization and hybridization detection . In this review, 2 masks designs are proposed. The first mask is the lateral nanogap with gold electrode and the second mask is for pad gold electrode pattern. Lateral nanogap is introduced in the fabrication process using silicon for nanogap and gold for electrode. Conventional photolithography and E- Beam lithography techniques are used to fabricate this nanogap (NG) based on the standard CMOS technology and the characterization of its conductivity together with its effect during sensing is investigated in this research ...
Introduction: HER2 gene amplification or overexpression occurs in 15% to 25% of breast cancers and has implications for treatment and prognosis. The most commonly used methods for HER2 testing are fluorescence in situ hybridization (FISH) and immunohistochemistry. FISH is considered to be the reference standard and more accurately predicts response to trastuzumab, but is technically demanding, expensive, and requires specialized equipment. In situ hybridization is required to be eligible for adjuvant treatment with trastuzumab in Australia. Bright-field in situ hybridization is an alternative to FISH and uses a combination of in situ methodology and a peroxidase-mediated chromogenic substrate such as diaminobenzidine [chromogenic in situ hybridization (CISH)] or multimer technology coupled with enzyme metallography [silver-enhanced in situ hybridization (SISH)] to create a marker visible under bright-field microscopy. CISH was introduced into diagnostic testing in Australia in October 2006. SISH ...

TY - JOUR. T1 - A double labeling technique for performing immunocytochemistry and in situ hybridization in virus infected cell cultures and tissues. AU - Gendelman, Howard E.. AU - Moench, Thomas R.. AU - Narayan, Opendra. AU - Griffin, Diane E.. AU - Clements, Janice E.. PY - 1985/1/1. Y1 - 1985/1/1. N2 - This report describes a combined immunocytochemical and in situ hybridization procedure which allows visualization of cellular or viral antigens and viral RNA in the same cell. Cultures infected with visna or measles virus were fixed in periodate-lysine-paraformaldehyde-glutaraldehyde, stained by the avidin-biotin-peroxidase technique using antibodies to viral or cellular proteins and then incubated with radiolabeled specific DNA probes (in situ hybridization). The immunoperoxidase stain was preserved through the hybridization procedure. Nonspecific sticking of probes over peroxidase stained cells was prevented by incorporation of 0.1% Triton X-100 into the hybridization solution and the ...
In situ hybridization allows us to learn more about the geographical location of, for example, the messenger RNA (mRNA) in a cell or tissue. It can also tell us where a gene is located on a chromosome. Obviously, a detection system must be built into the technique to allow the cytochemist to visualize and map the geography of these molecules in the cells in question.. When in situ hybridization was first introduced, it was applied to isolated cell nuclei to detect specific DNA sequences. Early users applied the techniques to isolated chromosomal preparations in order to map the location of genes in those chromosomes. The technique has also been used to detect viral DNA in an infected cell. In situ hybridization of RNA has also been used to show that RNA synthesis (transcription) occurs in the nucleus, while protein synthesis (translation) occurs in the cytoplasm.. ...
Visualize Gene Expression & Genetic Variations in Tissues:. Applications of RNAscope® and BaseScopeTM ISH technology. The nervous system consists of numerous specialized cell types that remain to fully cataloged and characterized at the molecular level. Due to the high degree of structural and functional heterogeneity and the intricate spatial organization of these cells, it is of special importance to analyze gene expression in the presence of full morphological and spatial contexts. Due to the lack of specific antibody reagents, especially for lncRNAs, G-protein coupled receptors (GPCRs), and ion channels, mapping of specific transcripts by in situ hybridization offers an excellent alternative approach. The RNAscope® assay provides a powerful method to detect gene expression within the spatial and morphological tissue context. BaseScopeTM is a novel in situ hybridization technology that allows visualization of splice junctions between adjacent exons and/or retained introns in highly specific ...

I have an In Situ Hybridization question for you guys and gals. Im currently performing In Situ HPV and EBV tests using an automated machine called the XT by Ventana. The tissue is parrifin embedded, cut at 4 microns and place on charged slides. NBT/ BCIP is used as our chromogen. I am beginning to notice some background staining that varies in intensity. When it occurs on our QC slide, it can be strong enough to fail a run. The background resembles a blue haze that can cover the tissue making interpretation difficult. At other times the blue haze surrounds the tissue rather than covering it which makes me believe that there could be some sort of hydrophobic or other chemical rxn taking place to shield the tissue. Im not certain if these two problems are related, but both occur completely random and always vary in intensity. If I can find the culprit of this problem it would lead to cleaner slides and more conclusive resulting. If anybody can help it would be much appreciated. Thanks P.S. ...

In this study we used quantitative RT-PCR (qPCR) in a large panel of adult rat brain and peripheral tissues (Figure 1), to further refine the expression profile of the Slc6a17 gene. The highest expression levels of Slc6a17 mRNA were found in hindbrain, various brain cross sections, cerebellum, spinal cord, brain stem and hypothalamus, while very low or no expression was seen in the peripheral tissues with the exception of epididymis. Consequently, the Slc6a17 transporter is highly and selectively expressed in the CNS of adult rat.. Abundant mRNA expression of Slc6a17 in adult and embryonic rat CNS has previously been shown using in situ hybridization. Consistent results indicated restricted expression exclusively in neurons, both glutamatergic and subsets of GABAergic [4, 9, 15-17]. Our results from in situ hybridization (Figure 3) shows that the mouse Slc6a17 gene has similar expression pattern as previously seen in rat, with high expression in mouse forebrain and midbrain and lower expression ...

The amplicon on 8p11.2 is reported to be found in up to 10% of breast carcinomas. It has been demonstrated recently that this amplicon has four separate cores. The second core encompasses important oncogene candidates, including the fibroblast growth factor receptor 1 (FGFR1) gene. Recent studies have demonstrated that specific FGFR1 amplification correlates with gene expression and that FGFR1 activity is required for the survival of a FGFR1 amplified breast cancer cell line. FGFR1 amplification was analysed in tissue microarrays comprising a cohort of 880 unselected breast tumours by means of chromogenic in situ hybridisation using inhouse-generated FGFR1-specific probes. Chromogenic in situ hybridisation signals were counted in a minimum 30 morphologically unequivocal neoplastic cells. Amplification was defined as |5 signals per nucleus in more than 50% of cancer cells or when large gene copy clusters were seen. FGFR1 amplification was observed in 8.7% of the tumours and was significantly more
The purpose was to evaluate and compare 5 different HER2 genetic assays with different characteristics that could affect the performance to analyze the human epidermal growth factor 2 (HER2) gene copy number under low and high throughput conditions. The study included 108 tissue samples from breast cancer patients with HER2 immunohistochemistry (IHC) results scored as 0/1+, 2+, and 3+. HER2 genetic status was analysed using chromogenic in situ hybridization (CISH) and fluorescence in situ hybridization (FISH). Scoring results were documented through digital image analysis. The cancer region of interest was identified from a serial H&E stained slide following tissue cores were transferred to a tissue microarrays (TMA). When using TMA in a routine flow, all patients will be tested for HER2 status with IHC followed by CISH or FISH, thereby providing individual HER2 results. In conclusion, our results show that the differences between the HER2 genetic assays do not have an effect on the analytic ...

Figure 1. HCN4 expression during embryogenesis (A) In situ hybridization analysis reveals HCN4 is expressed in the developing head and along the dorsal midline at the completion of neurulation embryos (NF stage 21 lateral and frontal views). At early tailbud stages, HCN4 expression is observed primarily in the craniofacial region, in 2 stripes along the neural tube, and in the developing somites. This expression pattern is maintained as development progresses (NF stage 25, lateral and anterior/ventral views). At NF stage 26, HCN4 mRNA begins to be expressed on the left side of the developing heart field (arrow; lateral and ventral views). Expression becomes bilateral beginning at NF stage 27/28 (arrows; lateral and ventral views) but remains more highly expressed on the left side of the body. Scale bars = 200μm. (B) As cardiogenesis progresses during tadpole stages (NF stages 29-39, lateral and ventral views, arrows denote heart), HCN4 expression is diffusely present in the developing ...
