PPT-Lab # 6 ELISA Enzyme – Linked

Immuno Sorbent Assay Definition The ELISA can be used both qualitatively and quantitatively to measure antigen antibody binding Depending on what variation you use it will detect antigen hormones enzymes microbial antigens illicit drugs or antibody anti HIV in the screening test for HIV infection in body fluids or tissue culture supernatant.

ELISA stands for Enzyme-Linked Immuno sorbent Assay.. ELISA is an immunological assay that is used to detect the presence of an antigen or antibody in a sample. . Principle. Types. Labeling technique. ELISA Principle. An enzyme conjugated with an Ab reacts with a colorless substrate to generate a colored reaction product. Substrate is known as chromogenic substrate. Assay (ELISA). Enzyme Linked . Immunosorbent. Assay (ELISA). Term Was Coined By . Engvall. and . Pearlmann. in 1971. Similar To RIA, Except No Radiolabel. Can Be Used To Detect Both Antibody and Antigen.
