Protein A, Biotinylated (S. Aureus, Cowan strain)
Description
Biotinylated Protein A (B-2001), isolated from S. aureus, is a 41 kDa protein which binds to the Fc portion of most immunoglobulins. This interaction is neither species specific nor isotype specific, as Protein A has been shown to bind IgG from a variety of species. Protein A can also interact with IgA, IgM and subclasses of IgG from different species.

Technical Information
Biotinylated Protein A is used in many systems as a substitute for a biotinylated second antibody. However, in some applications, Biotinylated Protein A may bind to endogenous immunoglobulin in the tissue producing background. In addition, Biotinylated Protein A may not bind to the species or class of primary antibody being employed. For routine immunohistochemical staining we recommend using biotinylated anti-immunoglobulins.
