Recombinant Streptococcal Protein G, r-SPG

Recombinant Staphylococcal Protein G, r-SPG
General description
Recombinant Protein G is a preparation of streptococcal protein G expressed in E. coli. Protein G binds to the Fc portion of immunoglobulin G subclasses (IgGs) from a broad range of species including human and mouse, and does not bind IgA, IgE, IgM or serum albumin.

Application: Protein G binds to the constant region of many species of immunoglobulin G. It can be used to detect, quantify and purify IgG antibodies and antibody/antigen complexes. Recombinant Protein G contains only IgG binding domains. The albumin-binding domain as well as cell wall and cell membrane binding domains have been removed to ensure the maximum specific IgG binding capacity.
Limitations: For LABORATORY RESEARCH USE ONLY and is not approved for use in humans or clinical.
