Question

Quizplus · Accepted Answer

IgM is the best choice as it has a high valency, meaning it has multiple binding sites for the antigen, which leads to crosslinking and aggregation of the antigen. This allows for effective agglutination despite the electrostatic repulsion between particles. IgG is also effective, but IgM is generally more efficient. IgA and IgE are not commonly involved in agglutination reactions.
