Abstract
A common antigen (Kunin) purification method is described. The preparation obtained was highly antigenic, as shown by hemagglutination and its inhibition, and immunogenic in rabbits. Chemical analysis demonstrated the presence of an L-phosphoglyceride of the cephalin type, protein, glucosamine, acetyl and glucose. The antigen had the character of an acidic polymer. It readily forms salt linkages with lysozyme. Phospholipase A induced the release of myristic, palmitic and stearic acids. It also destroyed both the antigenicity and immunogenicity of common antigen.
