Confirmed reactivity: Protein A from Staphylococcus aureus - Additional Information
-
Additional information: Antibodies were isolated from immune eggs, affinity purified on a protein A column and conjugated to N- hydroxysuccinimide (NHS)-activated agarose beads, Beads were washed extensively with after the blocking of the residual NHS sites Additional information (application): The specific activity of the anti-protein A-agarose was determined, For this lot, 1,1 mg protein A bound per ml agarose - Background
-
Background: Protein A is a surface protein of S. aureus which binds IgG molecules by their Fc region. In serum, the bacteria will bind IgG molecules in the wrong orientation on their surface, which hinders opsonization and phagocytosis. Mutants of S. aureus lacking protein A are more efficiently phagocytosed in vitro and mutants in infection models have diminished virulence. Due to its affinity for the Fc region of many mammalian immunoglobulins, protein A is considered a universal reagent in biochemistry and immunology.
