[Alloantigens of the formed elements of dog blood].

Absorption experiments showed that red blood cells of the dog contain some platelet antigens and only few leukocyte antigens. Canine platelets bear some leukocyte antigens. The main red blood cell antigens of dogs (DEA I. I. and 1.2) were detected in platelets and leukocytes, while other ones, weak red blood cell factors, were detected only in platelets. The lymphocytotoxic test showed, after separation of dog lymphocytes into T and B cells, that some antileukocyte sera including the samples directed against A and B series antigens of DLA system detect B lymphocyte-specific factors.
