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.

Source：Human FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag (FCM-H5286) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M) (Accession # P55899-1 (FCGRT) & P61769-1 (B2M)).
Molecule：FcRn (FCGRT & B2M)
Synonyms：FcRn,FCGRT & B2M
Species：Human
Tag：His Tag & Strep Tag
Expression Systems：HEK293
Expression Rigeion：Ala 24 - Ser 297 (FCGRT) & Ile 21 - Met 119 (B2M)
Characteristics：Human FCGRT&B2M Heterodimer Protein, His Tag&Strep II Tag, produced by co-expression of FCGRT and B2M, has a calculated MW of 31.2 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 33 kDa (FCGRT) and 13 kDa (B2M) respectively due to glycosylation.
Endotoxin Level：Less than 1.0 EU per ug by the LAL method.
