It has been utilized for quantitative assay of hormones, drugs, hepatitis B surface antigens, IgE and viral antigens, etc. They have the added advantages of not needing radioisotopes or a radiation -counting apparatus The various tests like Elisa, electrophoresis, and radioimmune assay, etc., all use the principles of microbiology to identify the type of disease. Product lines include a wide range of immunoassay reagents and antibodies used in assays such as, but not limited to, ELISA, immunohistochemistry (IHC), western blotting, flow cytometry (FACS), immunofluorescence and. The first clue in unraveling this mystery was the discovery of an enigmatic serum protein named Australia antigen 50 years ago by Baruch Blumberg. With inhibition of antigen binding, a radioimmune assay was developed for antibody detection. Measurement of radiation can be remarkably precise. The substance or antigen (a foreign substance in the body that causes antibody production) to be measured is injected into an animal, causing it to produce antibodies A radioimmunoassay (RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation radioimmune essay of immune complexes.A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for ….
