  • 蛋白结构(Molecular Characterization)

    IgG2 Fc Structure

    This protein carries no "tag".

    The protein has a calculated MW of 25.7 kDa. The protein migrates as 30-33 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 偶联(Conjugate)

    Unconjugated

  • 内毒素(Endotoxin)

    Less than 1.0 EU per μg by the LAL method.

  • 纯度(Purity)

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • 制剂(Formulation)

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍

Immunoglobulin G2 (IgG2) is a member of many immunoglobulin G developed and secreted by effective B cells. In wake of cutting by pepsin, IgG is divided into two F(ab)s with one antigen binding site and a high conserved Fc segment. The Fc segment bears a highly conserved N-glycosylation site. There are two members of IgG2: IgG2a and IgG2b. It was found that IgG2a was superior to IgG1 in activating complement. The glycosylation of the circulating immunoglobulin-γ (IgG) antibody molecules changes in rheumatoid arthritis. Ig gamma-2 chain Fc region contains two constant regions of IgG2 H chain (CH2, CH3).
