Recombinant Protein G Sepharose Online Inquiry

Product Name:Recombinant Protein G Sepharose
Synonym: Protein G
Size: 10 ml, 100 ml, 1L, and prepacked column
Description: 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)[1] cell surface protein that has found application in purifying antibodies through its binding to the Fab and Fc region. The native molecule also binds albumin, but because serum albumin is a major contaminant of antibody sources, the albumin binding site has been removed from recombinant forms of Protein G.Protein G is a bacterial cell wall protein expressing at the cell surface of some group C and group G Streptococcal strains. Protein G binds specifically to Fc regions of many mammalian immunoglobulins and is commonly used as affinity adsorbent to purify immunoglobulins (antibodies) and immunoglobulin subtypes from serum, hybridoma ascites, tissue culture supernatants and other biological fluids.
Storage: Store Recombinant Protein G Sepharose at 4-8℃ in 20% ethanol
