Name : Human LILRB4/CD85k/ILT3 Domain 1 Protein
Product Source :
Recombinant Human LILRB4/CD85k/ILT3 Domain 1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gln22-Thr118.[Accession | AAH26309.1]
Molecular Weight :
The protein has a predicted MW of 14.26 kDa. Due to glycosylation, the protein migrates to 14.5-20 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 LILRB4 Domain 1 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human LILRB4 Domain 1 is greater than 95% as determined by SEC-HPLC.
Background :
LILRB4,also known as CD85k and LIR-5, ILT-3, is an approximately 60 kDa transmembrane glycoprotein that negatively regulates immune cell activation. Mature human ILT-3 consists of a 238 amino acid (aa) extracellular domain with two Ig-like domains, a 21 aa transmembrane segment, and a 168 aa cytoplasmic domain with 3 immunoreceptor tyrosine-based inhibitory motifs (ITIM).LILRB4 is receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles.
Synonyms :
HM18; ILT3; ILT-3; LILRB4; LIR5; CD85K
