The Indirect Immunosorbent Assay Detects Antibodies Rather Than Antigens

Question

The indirect immunosorbent assay detects antibodies rather than antigens.

Accepted Answer

The indirect immunosorbent assay (ELISA) is a method used to detect the presence of antibodies in a sample. It involves coating a plate with an antigen, adding the sample containing antibodies, and then detecting the bound antibodies with a secondary antibody that is specific for the primary antibody. Therefore, the ELISA detects antibodies rather than antigens.
