Human LILRB3, Fc Tag (CDA-H5250) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Glu 443 (Accession # AAB68668 (P288R)).
Predicted N-terminus: Gly 24
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 72.8 kDa. As a result of glycosylation, the protein migrates as 90-115 kDa under reducing (R) condition, and 150 kDa under non-reducing (NR) condition (SDS-PAGE).
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Leukocyte immunoglobulin-like receptor subfamily B member 3 is also known as LILRB3,ILT-5 or CD85a. LILRB3 plays an role as receptor for class I MHC antigens, which activated upon coligation of LILRB3 and immune receptors, such as FCGR2B and the B-cell receptor. LILRB3 and LILRA6 represent a pair of inhibitory/activating receptors with identical extracellular domains and unknown ligands. LILRB3 can mediate inhibitory signaling via immunoreceptor tyrosine-based inhibition motifs in its cytoplasmic tail whereas LILRA6 can signal through association with an activating adaptor molecule, FcRγ.
