Why would ELISA test be used instead of a traditional biochemical test?
Homework Answers
Traditionally biochemical tests are carried out to test the quantity of particular substances in the biological system or to test the presence or absence of certain microorganisms etc. where as ELISA (Enzyme-linked immunosorbent assay), is an analytical biochemical assay, which uses antibodies or antigens covalently bound to enzymes to detect the presence of particular proteins associated with microorganisms.
These conjugated enzymes are selected based on their ability to catalyse the conversion of a substrate into a colored, fluorescent or chemiluminescent product. ELISA test is comparatively safer and less costly. Depending on the minute differences in the procedure, ELISA tests are of four types namely, indirect ELISA, direct ELISA, sandwich ELISA and competitive ELISA. When comparing to traditional biochemical tests, ELISA test is more specific. It uses an antigen or antibody coated microtitre, so that its specific antigen or antibody can be detected using the antigen-antibody binding principle.

ELISA Enzyme-Linked Immunosorbant Assay ELISA is a rapid test used for detecting or quantifying antibody (Ab) binding against viruses, bacteria and other materials or antigens (Ag). Can detect antibody antigen interaction. 96-well plates are made of polystyrene and are coated with either antigen or antibody. The function of the plate has to hold the immobilized either antigen or antibody. Legend for diagram below: Ag = antigen E = enzyme Substrate interacts with enzyme to allow colorimetric detection...

Elisa Test The standard test for the HIV virus is the Elisa test, which tests for the presence of HIV antibodies. If an individual does not have the HIV virus, the test will come back negative for the presence of HIV antibodies 99.8% of the time and will come back positive for the presence of HIV antibodies 0.2% of the time (a false positive). If an individual has the HIV virus, the test will come back positive 99.8% of the...

True/False. A. The HER2 ELISA test can still be used to monitor breast cancer patients on the monoclonal antibody Herceptin because different antigen epitopes are targeted by the ELISA platform than are targeted by the drug. B. In light chain production, the B cell first attempts to generate the k light chain. If unsuccessful, the cell then generates the ʎ light chain. c. Positional cloning uses restriction fragment length polymorphism (RFLP) analysis to identify abnormal protein products of mutated genes
