Anti-FCGRT Antibody Picoband® Fluoro488 Conjugated

IgG receptor FcRn large subunit p51?is a?protein?that in humans is encoded by the?FCGRT?gene. This gene encodes a receptor that binds the Fc region of monomeric immunoglobulin G. The encoded protein transfers immunoglobulin G antibodies from mother to fetus across the placenta. This protein also binds immunoglobulin G to protect the antibody from degradation.?In addition, it is postulated that long-range cis inactivation of the?FCGRT?gene is responsible for hypercatabolism of IgG in myotonic dystrophy. The?FCGRT?gene is closely situated to the DMPK gene, which is mutant in DM.?

E. coli-derived human FCGRT recombinant protein (Position: Q56-E291) . Human FCGRT shares 70.2% and 68.9% amino acid (aa) sequence identity with mouse and rat FCGRT, respectively.

Binds to the Fc region of monomeric immunoglobulins gamma. Mediates the uptake of IgG from milk. Possible role in transfer of immunoglobulin G from mother to fetus.
