Predicted N-terminus: Ala 24 (FCGRT) & Ile 21 (B2M)

蛋白结构(Molecular Characterization)

FcRn(Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M)) Q8SPV9-1 (FCGRT) & Q8SPW0-1 (B2M)

Cynomolgus / Rhesus macaque FcRn Heterodimer Protein (SPR verified), produced by co-expression of FCGRT and B2M, has a calculated MW of 32.3 kDa (FCGRT) and 13.1 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The reducing (R) protein migrates as 36 kDa (FCGRT) and 14 kDa (B2M) respectively due to glycosylation. Cynomolgus / Rhesus macaque FcRn Heterodimer Protein (SPR verified) sequences are identical.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)

FCGRT & B2M heterodimer protein (FcRn complex) consist of two subunits: p51 (equivalent to FCGRT), and p14 (equivalent to beta-2-microglobulin), and forms an MHC class I-like heterodimer. Fc fragment of IgG, receptor, transporter, alpha (FCGRT) binds to the Fc region of monomeric immunoglobulins gamma and mediates the uptake of IgG from milk. FCGRT possible role in transfer of immunoglobulin G from mother to fetus. Beta-2-microglobulin (B2M) is a component of the class I major histocompatibility complex (MHC) and involved in the presentation of peptide antigens to the immune system.
