简单介绍：
ProteinG(Active)protein(Histag)
详情介绍：
Brand MABSol®
Characteristics Recombinant Protein G Protein is fused with the polyhistidine tag at N-terminus and a single cysteine at C-terminus. The reducing (R) protein migrates as a 31 kDa polypeptide .Protein G Protein can bind to human IgG1 Fc .
Purity >98 % as determined by SDS-PAGE.
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
Background Protein G is an immunoglobulin-binding protein expressed in group C and G Streptococcal bacteria much like Protein A but with differing specificities. It is a 65- kDa (G148 protein G) and a 58 kDa (C40 protein G) cell surface protein that has found application in purifying antibodies through its binding to the Fc region. The native molecule also binds albumin, however, because serum albumin is a major contaminant of antibody sources, the albumin has been removed from this recombinant form of Protein G.
