Silver-staining of immunoprecipitates extends the sensitivity of the radial immunodiffusion assay by tenfold. This modification permits the quantification of apolipoproteins A-I, A-II, C, and E at levels of 0.2-1.0 mg/dl in plasma samples at a sensitivity threshold of 10 ng. The silver-enhanced radial immunodiffusion method is readily adapted from the standard method, simple and inexpensive to perform, and does not require costly instrumentation. These advantages make the modified RID assay an attractive alternative to other forms of immunoassay.
This lab activity is designed to study highly specific lock-key matching properties of antigen-antibody and how this highly specific interaction can be exploited as a tool for research and analysis. This study involves the use of an immunodiffusion technique in which antigen and antibody are allowed to diffuse in a solid agarose medium. When antigen and antibody meet, antigen-antibody complex is formed, which leads to precipitation. Antigen-antibody precipitate is formed in the zone where the concentration of the two matching pair reaches an optimal known as the zone of equivalence, which results in formation of a visible opaque precipitate region in agarose medium. Those regions of precipitation can be used for determination of concentration or titer of both antigen and antibody. The Antigen-Antibody Interaction kit is a hands-on study of both Ouchterlony Double Diffusion and Radial Immunodiffusion techniques. This kit also provides additional guidance materials for teaching other types of ...
Tumor antigens on the cell surface of thymic lymphoma cells from chemical- and virus-induced lymphomas of C57BL mice and virus-induced tumors of Wistar-Furth rats have been studied with the use of immunofluorescence on viable cells with rat, rabbit, and monkey antisera. In young mice given intrathymic injections of a murine leukemia virus, a new cell surface antigen can be detected as early as 2 to 4 days postinjection in some thymuses. Rat antisera to virus-induced rat thymic lymphoma cells gave a precipitin line in Ouchterlony double diffusion analysis when tested with virus isolated from plasma of tumor-bearing rats or from mouse lymphoma extracts. This reaction is due to the group-specific (internal) antigen of the murine leukemia viruses, since ether treatment of the virus preparations was required to obtain it. The results indicate that both radiation and certain chemicals may "activate" the same leukemia virus, which is endemic in this low leukemia strain.. ...
The defined antibody specificity is directed to albumin as tested against cat sera. In immunoelectrophoresis and double radial immunodiffusion (Ouchterlony), using various antiserum concentrations against appropriate concentrations of the immunogen, a single characteristic precipitin line is obtained which shows a reaction of identity with the precipitin lines obtained against cat serum and the purified albumin. As precipitating antiserum to identify or measure cat albumin by a variety of immunodiffusion techniques, including immunoelectrophoresis, single and double radial immunodiffusion (Mancini, Ouchterlony) and electroimmunodiffusion (Laurell). It has not been tested for use in nephelometry, ELISA or immunochemistry, but this does not exclude such use if proper controls are included ...
As a qualitative serum with an optimized protein content to study the normal protein composition of bovine serum. To identify or quantitate a normal serum protein component using a variety of immunodiffusion techniques including immunoelectrophoresis, single and double radial immunodiffusion and electroimmunodiffusion. As a reference serum in nephelometry and other automated precipitation techniques. As a blocking agent or as a negative control in non-precipitating antibody-binding assays e.g. in serodiagnostic immunofluorescence and immunoenzyme tests. This normal reference serum does not contain assigned values for individual proteins but can be used as an internal relative standard for quantitative protein assays such as double radial immunodiffusion (Mancini, Fahey), ELISA, Western immunoblotting and electroimmunodiffusion (Laurell), expressing the results obtained with the serum sample under investigation as a percentage of the protein concentration in the normal reference serum ...

i. Reaction of identity: Antigens in two wells are identical (Agl and Ag2). So the reaction with the antibody results in a precisely similar precipitin lines. The precipitin lines dont cross, but form a continuous line. Fusion of the two precipitin lines indicates that the antibody is reacting with epitopes commonly present on the two antigens. ii. Reaction of non-identity: Two non-identical antigens (Agl and Ag3) are in the antigen wells while the antibody well has antibodies to both the antigens. The two antigen-antibody precipitin lines formed differ from each other. Hence the two precipitin lines completely cross (intersect) each other. iii. Reaction of partial identity: The antigenic determinants in the antigens of two wells are partially shared (Agl and Agla). Hence the antibody reacts with both the antigens and forms lines that do not form a complete cross. The precipitin line crosses in only one direction. The extended precipitin line is referred to as a spur. The spur indicates that ...

Pulmonary tuberculosis (PTB) is global disease affecting about one third of the worlds population with its attendant mortality and morbidity. Acute phase proteins have been used in monitoring the progression of infections but not in relation to PTB in this environment. The levels of total protein, albumin, α-2-macroglobulin, transferrin, and haptoglobulin were determined in 23 patients with PTB and 17- age / sex matched PTB-free controls using spectrophotometric and immunodiffusion methods respectively. The result showed that α-2-macroglobulin was significantly raised in PTB patients compared with controls ( ...
Alternative methods are being sought to measure the potency of influenza vaccines. Label-free technologies that do not require the use of hemagglutinin (HA)-specific antisera are particularly attractive as the preparation of antiserum delays availability of potency reagents. The objective of these experiments was to evaluate the use of a Corning Epic® label-free method to quantify functional influenza hemagglutinin in rHA preparations. The method was optimized to quantify recombinant HA (rHA) of B/Brisbane/60/2008 (B/BR/08). Fetuin was immobilized onto plates and the change in wavelength of refracted light measured using an Enspire (Perkin Elmer) instrument. The change in wavelength measured in response to addition of rHA of B/BR/08 was proportional to its concentration and was optimal in the presence of native rHA conformations. However, the assay was strain-dependent and did not correlate with HAU measured using turkey red blood cells. The Corning Epic® label-free method is suitable for quantifying

The complex antigenic properties of adenovirus-soluble complete and incomplete hemagglutinins were utilized to study the specificity of adenovirus anti-hemagglutinin sera in immunodiffusion and counterimmunoelectrophoresis tests. Pentons, penton dimers, fiber dimers, and/or dodecons of adenovirus types 2, 3, 5, 7a, 8, and 11 were extensively purified by ion-exchange and exclusion chromatographies. Components were determined to be purified proteins by immunologic, electron microscopic, and polyacrylamide gel electrophoretic criteria. Specific antigenic components were identified by immunoelectrophoresis and by various biologic characteristics. Rabbit antisera prepared against these hemagglutinating components were type-specific in standard serologic, Ouchterlony immunodiffusion, immunoelectrophoretic, and counterimmunoelectrophoretic tests. Counterimmunoelectrophoresis was particularly well suited to a rapid identification and typing of adenovirus isolates for diagnostic purposes.. ...
Antisera were raised against rods of 17 named Arthrobacter and Aureobacterium strains. Antigenic relationships between these strains, other soil bacteria and new Arthrobacter isolates from several soils were studied, using agglutination, immunodiffusion, immunofluorescence and ELISA techniques. Many of the named Arthrobacter species had common antigens, and there were also common antigens amongst named Arthrobacter strains and many fresh Arthrobacter isolates. Agglutination, ELISA and immunofluorescence tests revealed greater antigenic differences between the named strains than did immunodiffusion tests. Serological similarities between the 17 named strains and the fresh Arthrobacter isolates were calculated using S coefficients. The occurrence of named strains in serogroups based on immunodiffusion data supported the taxonomic scheme for arthrobacters in Bergey's Manual of Systematic Bacteriology. The distribution of soil isolates in serogroups resembled that in groups based on numerical analysis
Evidence exists that C is involved in the coagulation process (Zimmerman et al., J. Exp. Med., No. 6, 1971). It has been reported that C3 (β1C/β1A) is significantly depressed in most patients with DIC (Tomar et al., Thromb. Diath. Haemorrh., 3: 27, 1972). In the present study C3 and C4 were quantitated by single radial immunodiffusion in the plasma of patients suffering mostly from severe septic and traumatic conditions with and without shock. Examinations including detailed coagulation studies were performed on 30 selected patients and 14 showed characteristic signs of DIC. C3 was markedly diminished in 13, C4 in 9 of the 14 DIC patients. In patients with septicemia but without DIC, a larger variation of results was found. In this group, depressions of C3 were observed in 6, and of C4 in 3 of 10 cases and seemed to occur more frequently when the condition was complicated by shock.. ...
Twenty cats with FIP and twenty with FIV were studied. The objective of the present study was to establish the diagnostic value of these two tests in both diseases. Correlation between AGP and Albumin/Globulin ratio (A/G) and CD4/CD8 ratio were analyzed in both groups.. FIV was confirmed by serology and PCR (Polymerase Chain Reaction). FIP was confirmed by histopathology (vasculitis and perivasculitis). In addition to the evaluation of the clinical signs blood chemistry, hematology and other complementary diagnostic methods. CD4/CD8 by flow cytometry and AGP test were performed in order to establish the diagnostic value of these two tests in both diseases. CD4/CD8 ratio was performed with: 8100-01 Sowthern Biotechnology, anti CD4 Vpg 34, Willett, Glasgow University, anti CD8, VPG9, Willett, Glasgow University and Fluorescent antimouse IgG Southern Biotechnology, Becton and Dickinson Facs Scan Citometer.

A glycoprotein with an apparent 340,000 mol wt (gp 340K) was isolated from rat kidney saline-soluble extract by ammonium sulfate precipitation, DE 52 ion-exchange cellulose chromatography, concanavalin A affinity column, Sephacryl S-300 gel filtration, and discontinuous polyacrylamide gel electrophoresis (PAGE). The relative purity of gp 340K was examined by double immunodiffusion analysis, disc PAGE, and immunoelectrophoresis. Injection of rabbit gp 340K antiserum into pregnant rats during the organogenetic period induced abnormal embryonic development, fetal growth retardation, and embryonic death. Antiserum against the immunocomplexes isolated by immobilized protein A also produced the same embryotoxic effects. The biologic effects of the antisera appeared to be dose dependent. Defects such as anophthalmia, hydrocephaly, exencephaly, cleft palate, cleft lip, and some cardiovascular anomalies were observed. The most frequently observed anomaly was anophthalmia. Immunofluorescent localization ...
Previous studies demonstrated the cross antigenicity between endothelial and epithelial basement membranes. In the present study we have isolated and characterized chemically and immunologically the antigenic components of basement membranes from the glomerulus, alveolus, and lens capsule. The basement membranes were solubilized by reduction and alkylation and antisera prepared in rabbits. On immunodiffusion two precipitin lines of identity form when antiserum to either reduced and alkylated glomerulus or lens-capsule basement membranes is reacted with both antigens. Reduced and alkylated alveolus basement membrane reacts similarly with both antisera. Upon fractionation of the basement membranes two antigenic components are obtained. One is ...
Glyceraldehyde 3-phosphate dehydrogenases (EC 1.2.1.12 and 1.2.1.13) have been purified from the seed, root, etiolated, and green shoot of peas (Pisum sativum). These enzymes are tetramers of 140,000 daltons, with subunits of 35,000 daltons. The enzymes differ in isoelectric point. The seed enzyme has a pI of 5.1, and the root enzyme has a pI of 4.5. The cytoplasmic enzyme from etiolated shoots is slightly acidic with a pI of 5.7 to 6.1 and is found in two separable forms. The chloroplast enzyme (from green shoots) is most basic with a pI of 8.0.. In immunodiffusion experiments, the seed, root, and cytoplasmic enzymes of the etiolated shoot share antigenic homology, while the chloroplast enzyme does not cross react antigenically with the extra-chloroplast enzymes. The antiserum to the pea chloroplast enzyme did, however, cross react with glyceraldehyde 3-phosphate dehydrogenase purified from the spinach chloroplast. Therefore, the chloroplast enzyme is significantly different from the ...

Summary: Cytoplasmic and cell-wall antigens and antisera were prepared from four Phytophthora species, and cell-wall antigens were prepared from two Pythium species. Immunodiffusion of the Pythium and Phytophthora cell-wall antigens showed that the two Pythium species did not cross-react with the Phytophthora cell-wall antisera. Immunodiffusion analysis of both cell-wall and cytoplasmic antigens of Phytophthora revealed some degree of specificity between species but not between A1 and A2 mating types in Phytophthora cinnamomi. Species specificity was improved by using indirect fluorescent antibody techniques and by the use of cross-absorbed sera. Agglutination and quantitative precipitation techniques did not significantly improve specificity.
