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.

FAQs for Protein A Antibody (FAB99761CL1). (Showing 1 - 1 of 1 FAQ).

1. During my master thesis, I am working on a large scale ribosome affinity purification in Trypanosoma brucei. Unfortunately, we have some problems with the present antibody (IgG against protein A, extracted from chicken). Therefore, we are searching a better and more efficient alternative. Ideally it is extracted from guinea pig, rat, mouse or rabbit. Searching suitable antibodies, I found you have some in your range of products. Since we need to work large scale and will need a bigger amount of antibodies the next months, we would like to get the possibility to test the new antibodies first. Therefore I would like to ask for an aliquot for testing. You would really help me finding an good alternative!
