FcRn is expressed by the vascular endothelium, several epithelial cell types, and hematopoietic cells including several innate immune cell types and B cells (2). FcRn mediates recycling and transcytosis of IgG, resulting in protection of IgG from catabolism and an extended serum half-life of IgG relative to other antibody isotypes (3). In addition, FcRn transports IgG across the placenta and also mediates uptake of maternal IgG from milk, resulting in enhanced humoral immunity in the fetus and neonates (1,4,5). FcRn also plays an important role in initiation of adaptive immunity by transporting immune complexes to intracellular dendritic cell compartments for antigen processing and presentation to T cells (6-8). In addition to IgG, FcRn also binds albumin and similarly protects it from catabolism, leading to extended half-life and high plasma concentrations (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nalpha-chain; Fc fragment of IgG receptor and transporter; Fc fragment of IgG, receptor, transporter, alpha; FCGRN; FCGRT; FCRN; FcRn alpha chain; heavy chain of the major histocompatibility complex class I-like Fc receptor; IgG Fc fragment receptor transporter alpha chain; IgG receptor FcRn large subunit p51; immunoglobulin receptor, intestinal, heavy chain; major histocompatibility complex class I-like Fc receptor; Neonatal Fc receptor; neonatal Fc-receptor for Ig; transmembrane alpha chain of the neonatal receptor\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 40-50\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799818391721,"sku":"55546S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-55546s","provider":"Iright","version":"1.0","type":"link"}
