Splits of the HLA DR2 antigen.
The reaction of ninety DR2 positive persons with 20 anti-DR2 sera were studied. Four of the panel and members of two families did not react with two of these anti-DR sera and were considered to have the short-split "DR2.2". DR2 positive samples reacting strongly with all anti-DR2 were designated "DR2.1".
