[Immunochemical identification and physicochemical characteristics of human leukocytic beta 2-sialoglobulin (RAL-6)].

A new glycoprotein (RAL-6) was identified in human venous blood by immunochemical assay. During studies into the physicochemical properties, it was established that the glycoprotein has a mobility of beta 2-globulins and contains sialic acids. Study of RAL-6 content in tissue extracts from different organs of man and in biological fluids demonstrated the protein to be contained by pus extracts in a large quantity. The concentration of RAL-6 in hemolysates was found to be lowered in some of the diseases including those of the autoimmune nature.
