IgA AND IgM REACTING WITH STAPHYLOCOCCAL PROTEIN A

Abstract

52 Acta path, microbiol. scand. Section B. 79, 6 IgM in guinea pig antisera obtained 10 days after immunization with purified protein A, and IgA in human colostrum from apparently healthy mothers, reacted with protein A. These findings are consistent with antibodies to protein A having Fab‐ as well as Fc‐reactive. sites.
