Question

Quizplus · Accepted Answer

Indirect EIA is commonly used to detect antibodies. It relies on the binding of an antibody to a particular antigen, and the detection of that antibody through a secondary reaction with an enzyme-linked detection system. This can be useful for identifying disease-specific antibodies in patient serum or for monitoring the immune response to a particular pathogen or vaccine.
