Heterophile antibodies are IgM antibodies with affinity for sheep and horse red blood cells. They appear during the first week of infectious mononucleosis symptoms, 3–4 weeks after infection and return to undetectable levels 3 to 6 months after infection. Heterophile antibody is a fairly specific but insensitive test for EBV. It is present in ...

Heterophile antigens are antigens of similar nature, if not identical, that are present in different tissues in different biological species, classes, or kingdoms. [1] Usually different species have different antigen sets, but the hetereophile antigen is shared by different species.
The antibody that fails to react is known as the blocking antibody and prevents the precipitating antibody from binding to the antigens. Thus the proper precipitation reaction does not take place. However, when the serum is diluted, the blocking antibody is as well and its concentration decreases enough for the proper precipitation reaction to ...
A blocking antibody is an antibody that does not have a reaction when combined with an antigen, but prevents other antibodies from combining with that antigen. [1] This function of blocking antibodies has had a variety of clinical and experimental uses. The term can also be used for inhibiting antibody, prozone phenomenon and, agglutination ...
The antibody works by breaking the life cycle of the parasite, which is spread through mosquito bites. It targets immature parasites before they enter the liver where they can mature and multiply.
