A positive monocyte crossmatch and therefore anti-monocyte antibodies are negative factors in bone marrow and renal transplantation. When the monocyte antigens themselves can be recognized, matching for the antigens involved here may become a possibility. In order to find useful anti-monocyte sera as typing reagents, human sera were screened aganst panel cells. Several monocyte specific sera were obtained. These sera recognized two monocyte antigens, HMA-1 and HMA-2. No similarity with any of the HLA antigens was observed. Every individual tested was positive for at least one of these two monocyte antigens, suggesting that HMA-1 and HMA-2 constitute a diallelic system.
