  • Relevance

    S.aureus 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.
  • Cellular localization

    Customer reviews and Q&As


    Thank you for contacting us.

    Please find below the information I managed to collect by contacting the sources of the Anti-Staphylococcus aureusand the Anti-Streptococcus agalactiaeantibodies we have in our catalog :

    Anti-Staphylococcus aureus:
    https://www.abcam.com/ab23568 shows no reactivity to any streptococcus sp., mycoplasma sp. or corynebacteria sp.

    Unfortunately, ab35192 has not been specifically tested against streptococcus so we are unable to guarantee it won’t react to S. agalactiae.

    ab68950, ab68952, ab68954: These Staphylococcus aureus polyclonal antibodies are not absorbed for related microorganisms and so therefore could cross react with related bacteria such as Staph. Epidermidis.

    MLS : Staphylococcus aureus: We do not have an antibody that is specific to Staph. aureus but does not have crossreactivity to Staph. epidermidis.

    Anti-Streptococcus agalactiae:
    https://www.abcam.com/ab21126 has weak crossreactivity with Strep. dysgalactiae and does not cross-react with Strep. uberis, Strep. bovis, Strep. faecalis, Staph. aureus, Mycoplasma bovis, Mycoplasma californicum, Mycoplasma bovigenitalium, E. coli or Corynebacterium bovis.

    I hope this information is helpful to you. I am still waiting for more information about ab128711 (Anti-Streptococcus agalactiae antibody [224/46]).
    Please do not hesitate to contact us if you need any more advice or information.
