What types of antigens are most susceptible to the action of precipitins?

Question

Quizplus · Accepted Answer

Precipitins are antibodies that react with soluble antigens in a way that forms precipitates. Therefore, soluble antigens such as proteins and peptides are most susceptible to the action of precipitins. Antigens on bacterial surfaces or the surface of viral particles are more likely to be targeted by other types of antibodies such as agglutinins or neutralizing antibodies, while host cellular antigens are typically recognized by cell-mediated immunity rather than precipitins.
