Demonstration of Diego (Dib) and Scianna (Scl) antigens on phagocytic leukocytes of the blood.

The high-incidence erythrocyte antigens Dib and Scl have been demonstrated on leukocytes, using an antibody absorption technique. Tests with separated platelets, lymphocytes and neutrophils indicate that these antigens are restricted to the phagocytic leukocytes. Studies using the same methodology do not show Lan or Coa antigens on leukocytes.
