Name : Biotinylated Human NKG2A&CD94 Protein
Product Source :
Recombinant Biotinylated Human NKG2A&CD94 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Arg100-Leu233(NKG2A)&Ser34-Ile179(CD94).[Accession | P26715-1(NKG2A)&Q13241-1(CD94)]
Molecular Weight :
The protein has a predicted MW of 17.9 kDa (CD94)&18.3 kDa (NKG2A). Due to glycosylation, the protein migrates to 33-48 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 Biotinylated Human NKG2A&CD94 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human NKG2A&CD94 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Human NKG2A&CD94, His Tag at 0.5μg/ml (100μl/Well) on streptavidin (5μg/ml) precoated plate. Dose response curve for Anti-NKG2A Antibody, hFc Tag with the EC50 of 2.5ng/ml determined by ELISA.
Background :
The ligand-receptor assignment between HLA-G and NKG2A/CD94 is dependent of the amino acid composition in the HLA-G heavy chain. Understanding the biophysical basis of receptor-mediated events that lead to NK cell inhibition would help to remove non-tumor reactive cells and support personalized mild autologous NK cell therapies.
Synonyms :
CD159a; NKG2A; NKG2-A; CD94; NKG2A&CD94
