WebAgglutination, the formation of antigen-antibody complexes, is an important function of antibodies. Which isotype of antibody has the potential to agglutinate antigens well because it is able to bind to more antigens than any other? \begin{tabular}{c} IgA \\ \hline IgD \\ \hline IgE \\ \hline lgG \\ \hline IgM \end{tabular} WebAntibody isotypes are categorized according to differences in their amino acid sequence in the constant region (Fc) of the antibody heavy chains. The antibody isotypes IgG and IgA are further grouped into subclasses (e.g., human IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2) based on additional small differences in their amino acid heavy chain sequences.
