FcRn Protein (AA 24-297) (His tag,Strep Tag)

Catalog No. ABIN2181085

Product Details

Target: FcRn (IgG receptor FcRn (FcRn))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 24-297

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This FcRn protein is labelled with His tag,Strep Tag.

Brand: MABSol®

Sequence: AA 24-297

Characteristics: Human FcRn / FCGRT & B2M heterodimer protein, 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 his-tag at the C-terminus and subunit Beta-2 microglobulin (B2M) is fused with Strep II-tag at the C-terminus. The predicted N-terminus is Ala 24(FCGRT) & Ile 21(B2M). The reducing (R) protein migrates as 33 kDa (FCGRT) and 13 kDa (B2M) respectively due to glycosylation.

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.
