The FCGRT protein is a cell surface receptor that conveys passive humoral immunity through the selective uptake of monomeric IgG in milk. It binds IgG at the intestinal epithelium and forms an FcRn-IgG complex that is transcytosed across the epithelium, releasing IgG into the blood or tissue. FCRN-B2M Heterodimer Protein, Human (HEK293, His) is a recombinant protein dimer complex containing human-derived FCRN-B2M Heterodimer protein, expressed by HEK293 , with C-His labeled tag. FCRN-B2M Heterodimer Protein, Human (HEK293, His), has molecular weight of ~35 & 12 kDa, respectively.
