[Comparative physicochemical and immunochemical study of 3 soluble antigens in human leukocytes]

Immunochemical assay was used to identify 3 soluble leukocyte antigens in leukolysates. According to the common classification these antigens were denoted as RAL-3, RAL-4, and RAL-5. The physiochemical properties of these antigens were studied as was their content in extracts of different tissues and in biological fluids.
