Product Overview:
Recombinant Human FCAMR(Leu17-Arg450) fused with His tag at C-terminal was expressed in CHO.
Fc alpha/mu Receptor (FCAMR), designated CD351, is an approximately 60 kDa transmembrane protein that serves as a receptor for IgA and IgM immunoglobulins. Mature human FCAMR consists of a 434 amino acid (aa) extracellular domain with one Ig-like domain, a 21 aa transmembrane segment, and a 61 aa cytoplasmic domain. Within the ECD, human FCAMR shares 51% aa sequence identity with mouse and rat FCAMR. Alternative splicing generates additional isoforms that are truncated following the Ig-like domain, are truncated before the transmembrane segment, or carry a 9 aa deletion and a substitution of the transmembrane segment. FCAMR is expressed on B cells, macrophages, and kidney mesangial cells. It binds to both IgA and IgM in immune complexes but not to monomeric immunoglobulin. FCAMR participates in pathogen clearance as well as foam cell formation by mediating the internalization of IgM-opsonized microbes and oxidized LDL-containing particles.

Predicted N Terminal:
Lyophilized from a 0.2 μm filtered solution in PBS.
Measured by its binding ability in a functional ELISA. When Human IgM is immobilized at 2.5 μg/mL, 100 μL/well, the concentration of Recombinant Human Fc alpha /μ R that produces 50% of the optimal binding response is approximately 0.12-0.72 μg/mL.
