Rhesus macaque LILRB1/CD85j/ILT2 Protein
Recombinant Rhesus macaque LILRB1/CD85j/ILT2 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Met1-His474.[Accession | NP_001035762.2]
The protein has a predicted MW of 75.2 kDa. Due to glycosylation, the protein migrates to 80-90 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Rhesus macaque LILRB1, hFc Tag captured on CM5 Chip via Protein A can bind Rhesus macaque HLA-G&B2M&Peptide (RIIPRHLQL) Tetramer, His Tag with an affinity constant of 1.74 nM as determined in SPR assay (Biacore T200).
Anti-LILRB1 Antibody immobilized on CM5 Chip can bind Rhesus macaque LILRB1, hFc Tag with an affinity constant of 47.69 nM as determined in SPR assay (Biacore T200).
LILRB1, also known as CD85j and ILT2, is a 110 kDa transmembrane glycoprotein in the LILR immunoregulatory protein family. Mature human LILRB1 consists of a 438 amino acid (aa) extracellular domain (ECD) with 4 tandem Ig-like domains, a 21 aa transmembrane segment, and a 168 aa cytoplasmic domain with 4 inhibitory ITIM motifs.LILRB1 is a receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles. Receptor for H301/UL18, a human cytomegalovirus class I MHC homolog. Ligand binding results in inhibitory signals and down-regulation of the immune response.
