Recombinant Human Transcobalamin II Receptor/TCblR/8D6A/CD320 (C-Fc)
Recombinant Human Transcobalamin II Receptor is produced by our Mammalian expression system and the target gene encoding Ser36-Val231 is expressed with a Fc tag at the C-terminus. Bon Opus Cat. #CX62
BackgroundCD320 antigen is also known as 8D6 antigen，FDC-signaling molecule 8D6，Transcobalamin receptor and 8D6A. It is a single-pass type I membrane protein and containing two LDL-receptor class A domains. CD320 has been recently discovered and reported as a follicular dendritic cell (FDC) protein. CD320 can augments the proliferation of plasma cells precursors generated by IL-10. CD320 also founctions a receptor for the cellular uptake of transcobalamin bound cobalamin. Defects in CD320 are the cause of methylmalonic aciduria type TCblR (MMATC) which is a metabolic disorder.
FormulationLyophilized from a 0.2 μm filtered solution of 20mM Tris,150mM NaCl, pH 8.0.
