Custom Services Service: Protein G Purification Code: C005 Description: Protein G is a bacterial cell wall protein isolated from group G Streptococci. Like Protein A from Staphylococcus aureus, Protein G binds to most mammalian immunoglobulins primarily through their Fc regions. Native Protein G contains two immunoglobulin binding sites, as well as albumin and cell surface binding sites. In the recombinant form of Protein G, these albumin and cell surface binding sites have been eliminated to reduce nonspecific binding when purifying immunoglobulins W We will purify up to 100 mgs of your Sera, ascites fluid or tissue culture supernate by affinity chromatography using protein G coupled to agarose gels. This will produce an IgG fraction with purity greater than 95% IgG. Table 2.
