Human LILRB2, Fc Tag (CDD-H5259) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Val 461 (Accession # AAH36827).
Predicted N-terminus: Gln 22
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 74.4 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>90% 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.

Immobilized Human LILRB2, Fc Tag (Cat. No. CDD-H5259) at 1 μg/mL (100 μL/well) can bind Anti-LILRB2 Antibody, Human IgG1 with a linear range of 1-2 ng/mL (QC tested).
Leukocyte immunoglobulin-like receptor subfamily B member 2 (LILRB2) is also known as CD85 antigen-like family member D (CD85d), Immunoglobulin-like transcript 4 (ILT-4), Monocyte / macrophage immunoglobulin-like receptor 10 (MIR-10), which is a member of the the subfamily B class of LIR receptors. LILRB2 is receptor for class I MHC antigens. LILRB2 recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. LILRB2 competes with CD8A for binding to class I MHC antigens. LILRB2 / CD85d inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
