Question

Quizplus · Accepted Answer

Monoclonal antibodies have greatly improved the specificity of immunological tests as they are very specific for a single antigen and do not cross-react with other antigens, unlike polyclonal antibodies. Monoclonal antibodies are produced by fusing a single antibody-producing cell with a cancer cell to create a hybridoma cell, which produces identical antibodies. This allows for more precise and accurate testing. Electronics, enzymes, and radioactivity may aid in the detection of antibodies or antigens, but they do not necessarily improve the specificity of the test.
