CD3 is a member of the T cell receptor-associated CD3 complex. The monoclonal antibody CT-3 recognises a complex of at least three polypeptides of Mr 20, 19, and 17 kDa (two of which are N-glycosylated) on chicken T cells. The antibody also coprecipitates a polypeptide of 90 kDa from digitonin solubilised T cell lysates, which can be reduced to two polypeptides of Mr 50 and 40 kDa.
