- Mouse FcRn / FCGRT & B2M Heterodimer Protein
|Synonyms||FcRn,FCGRT & B2M|
|Characteristics||Mouse FcRn / FCGRT & B2M Heterodimer Protein, produced by co-expression of FCGRT and B2M, has a calculated MW of 33 kDa (FCGRT) and 14.7 kDa (B2M). Subunit FCGRT is fused with his-tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Twin-Strep tag at the C-terminus. The predicted N-terminus is Ser 22(FCGRT) & Ile 21(B2M). The reducing (R) protein migrates as 45-50 kDa (FCGRT) and 18 kDa (B2M) respectively due to glycosylation.|
|Endotoxin Level||Less than 1.0 EU per μg by the LAL method.|
|Purity||>95% as determined by SDS-PAGE.|
|Description||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.|
