Quizplus · Accepted Answer

Monoclonal antibodies are specific and can be engineered to bind to a wide range of targets, including proteins, cells, and other molecules. They have been used for a variety of applications, including detecting specific proteins on a cell membrane (A), triggering an immune response to cancer cells (C), detecting pregnancy (D), and treating cancer (E). However, monoclonal antibodies are not typically used as vaccines (B). Vaccines usually consist of weakened or dead pathogens or parts of pathogens to stimulate the immune system to produce antibodies against them.
