Protein G标记peroxidase/Agarose Beads/thiol/Biotin/Biotin

蛋白G是一种免疫球蛋白结合蛋白,在C群和G群链球菌中表达,与蛋白类似,但具有不同的特异性。它是一种65kDa(G148蛋白G)和58kDa(C40蛋白G)的细胞表面蛋白,通过与Fc区的结合在纯化抗体中得到了应用。然而,由于血清白蛋白是抗体来源的主要污染物,白蛋白结合位点已从重组蛋白G中移除。

重组蛋白质 G (rProtein G) 琼脂糖适合使用柱层析或免疫沉淀法的 IgG 抗体纯化。 这种包含基因改造型链球菌蛋白 G 的基质可消除血清白蛋白的结合,同时保持 IgG 同型的 Fc 域结合效率。rProtein G 在大肠杆菌中生产,纯化后,通过溴化氰共价固定在 4% 琼脂糖微珠上。和蛋白 A 相比,rProtein G 琼脂糖能结合的 IgG 同型更多。rProtein G 琼脂糖能结合 >18 mg 人 IgG/ml 凝胶。 在亲和层析中,rProtein G 琼脂糖的结合性能和稳定性使其可以提高速度,还可以重复使用。
