34.2 kDa (FCGRT) & 11.7 kDa (B2M)

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.

FcRn (FCGRT & B2M)

Biotinylated Human FCGRT&B2M Heterodimer Protein, His, Avitag, produced by co-expression of FCGRT and B2M, has a calculated MW of 34.2 kDa (FCGRT) and 11.7 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) and subunit Beta-2 microglobulin (B2M) contains no tag at the C-terminus. The reducing (R) protein migrates as 38-40 kDa (FCGRT) and 12 kDa (B2M) when calibrated against Star Ribbon Pre-stained Protein Marker respectively due to glycosylation.
