Name : Human LILRB3/CD85a/ILT5 Protein

Product Source :
Recombinant Human LILRB3/CD85a/ILT5 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gly24-Glu443.[Accession | O75022-1]

Molecular Weight :
The protein has a predicted MW of 50 kDa. Due to glycosylation, the protein migrates to 60-72 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-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.

Product Concentration :
Tris-Bis PAGE Human LILRB3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human LILRB3 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Human LILRB3, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Anti-LILRB3 Antibody, hFc Tag with the EC50 of 12.5ng/ml determined by ELISA.

Background :
Leukocyte immunoglobulin-like receptor subfamily B (LILRB3), also known as ILT5, LIR3, and CD85a, is an immunoglobulin superfamily member that is involved in immune regulation. Subfamily B members have cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs) that inhibit signaling events via phosphatase SHP-1.LILRB3 may act as receptor for class I MHC antigens. Becomes activated upon coligation of LILRB3 and immune receptors, such as FCGR2B and the B-cell receptor.

Synonyms :
CD85a; ILT5; ILT-5; LILRB3; LIR3; LIR3CD85A; LIR-3MGC138403; PIRB; HL9
