Cat#:RP-124AM;Product Name:Recombinant Protein G;Synonym:Protein G; Strepococcus strain G148; Staphylococcaceae; Streptococcus; G148; SPG; Staphylococcal protein G;Background:Protein G is an immunoglobulin-binding protein expressed in group C and G Streptococcal bacteria much like Protein A but with differing binding specificities. It is a 65-kDa (G148 protein G) and a 58 kDa (C40 protein G). Protein G shows a broader range of binding to IgG subclasses. ;Description:Recombinant Protein G expressed in E.coli has a predicted molecular weight of 28kDa. The recombinant protein G was purified using our unique purification methods.;Source:N/A;Molecular Characterization:N/A;Purity:N/A;Formulation:Recombinant Protein ­ lyophilised;Stability:3 years;Species Reactivity:Bacteria;Application:ELISA, IP;Storage:Store recombinant protein G at -20℃. ;Usage:For Lab Research Use Only;References:Sjobring U, Bjorck L, Kastern W, et al.
