WebThe valency of both the antigen and antibody refers to how many binding sites an antibody or antigen may have. One example of this is how IgM antibodies have ten binding sites (decavalent) whereas IgE antibodies only have two binding sites (bivalent). Therefore, IgM antibodies have a greater valency to IgE antibodies. tablecloth conferenceWebFeb 10, 2024 · Although it has lower affinity binding sites, but have more avidity towards the antigens.
