| 产品介绍 |
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)[1] 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 binding site has been removed from recombinant forms of Protein G. Recombinant protein G has a very high affinity for the Fc regions of IgG molecules. Immoblisation of protein G on beads creates an affinity resin which can be used to purify IgG fractions from crude serum, ascites fluid or cell cuture media.
Recomb Protein G 蛋白G是从G类Streptococci细菌中分离出来的胞壁蛋白，与多数哺乳动物的IgG Fc段结合（包括：人、山羊、绵羊、兔、豚鼠、马、猪、猴、小鼠等），分子量：22kDa。不与狗IgG结合、不结合人IgM、IgD、和IgA。 重组蛋白G（Recomb Protein G）已经除去了与白蛋白及细胞表面结合位点，减少了交叉反应和非特异性结合。因此，它比天然蛋白G和蛋白A有更大的亲和力。可以代替二
