Las 'aglutininas' son globulinas gamma(gamma globulinas), como los otros
anticuerpos, y son producidas por las mismas células que producen los
anticuerpos frente a otros antígenos.
La mayor parte de ellas son moléculas de inmunoglobulinas IgM e IgG. Cuando el

aparecen aglutininas anti-A en el plasma. Además, cuando el aglutinógenode
tipo B no está presente en los hematíes, aparecen unos anticuerpos, conocidos
como aglutininas anti-B, en el plasma. Los grupos sanguíneos comparten estas
aglutininas en su superficie. El grupo O, posee, aun este no teniendo
aglutinógenos, posee aglutininas anti-A y anti-B. El grupo A, posee aglutininas
anti-B y el grupo sanguíneo B posee aglutininas anti-A.
