Question

Expand the term ELISA.

Answer 1

ELISA stands for Enzyme Linked Immuno-Sorbent Assay. It is used to diagnose AIDS. It is based on the principle of Antigen-Antibody interactions. It is an extremely sensitive test that is used to detect antibodies (Ab) or specific antigens (Ag). Infection by pathogen can be detected by the presence of antigens (proteins, glycoproteins) or by detecting the antibodies synthesized against the pathogen.
