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：Rabbit FCGRT&B2M Heterodimer Protein, His Tag&Tag Free (FCM-R52W5) is expressed from human 293 cells (HEK293). It contains AA Ala 24 - Val 297 (FCGRT) & Val 22 - Tyr 120 (B2M) (Accession # ABY47597.1 (FCGRT) & ALR85722.1 (B2M)).
Molecule：FcRn (FCGRT & B2M)
Synonyms：FcRn,FCGRT & B2M
Species：Rabbit
Tag：His Tag
Expression Systems：HEK293
Expression Rigeion：Ala 24 - Val 297 (FCGRT) & Val 22 - Tyr 120 (B2M)
Characteristics：Rabbit FCGRT&B2M Heterodimer Protein, His Tag&Tag Free, produced by co-expression of FCGRT and B2M, has a calculated MW of 32.1 kDa (FCGRT) and 11.7 kDa (B2M). Subunit FCGRT is fused with a polyhistidine tag at the C-terminus and subunit Beta-2 microglobulin (B2M) contains no tag at the C-terminus. The reducing (R) protein migrates as 34 kDa (FCGRT) and 12 kDa (B2M) respectively due to glycosylation.
Endotoxin Level：Less than 1.0 EU per ug by the LAL method.
