Scientific Background
IgG receptor FcRn large subunit p51 (FCGRT) is a ~39 kDa protein. Cell surface receptor that transfers passive humoral immunity from the mother to the newborn. Binds to the Fc region of monomeric immunoglobulin gamma and mediates its selective uptake from milk. IgG in the milk is bound at the apical surface of the intestinal epithelium. The resultant FcRn-IgG complexes are transcytosed across the intestinal epithelium and IgG is released from FcRn into blood or tissue fluids. Throughout life, contributes to effective humoral immunity by recycling IgG and extending its half-life in the circulation.
Product Description
Efgartigimod (HX061056) is a research-grade recombinant antibody targeting IgG Fc fragment receptor transporter alpha chain. Produced in mammalian cells with native-like glycosylation. Highlights- Research Grade — For PK/PD studies, assay development, and ADA research.
- Native Glycosylation — Mammalian expression ensures native-like patterns.
