Recombinant Biotinylated Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer Protein,His-Avi Tag

Description :
Synonyms HLAE; sHLA-E; HLAE; MHC class I antigen E; MHC HLA-E alpha-1; MHC HLA-E alpha-2.1; MHC; QA1 Source Biotinylated Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus,tetramer is assembled by biotinylated monomer and streptavidin. It contains Gly25-Ile305(HLA-E*01:03), Ile21-Met119(B2M) and VMAPRTLVL peptide.[Accession | P13747(HLA-E*01:03)&P61769(B2M)&VMAPRTLVL] Molecular Weight The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity Blocking Data:Serial dilutions of Anti-NKG2A Antibody were added into Biotinylated Human HLA-E*01:03&B2M&Peptide (VMAPRTLVL) Tetramer, His Tag : Human NKG2A&CD94, mFc Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 0.15g/ml. Formulation Lyophilized from 0.22m 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 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
