RT Journal Article SR Electronic T1 “Protein A” from S. Aureus JF The Journal of Immunology JO J. Immunol. FD American Association of Immunologists SP 822 OP 827 VO 97 IS 6 A1 Forsgren, Arne A1 Sjöquist, John YR 1966 UL http://www.jimmunol.org/content/97/6/822.abstract AB Protein A was isolated from S. aureus and shown to precipitate about 45% of a pooled normal human γG preparation. In addition it was demonstrated that protein A reacts with myeloma γG-globulin, H chains from both normal and myeloma γG-globulins and the Fc fragment of normal γG-globulin. Thus, the reaction is not a true antigen-antibody reaction.
