Product Information Product Name Cat No. Specification Recombinant Human NKG2A&CD94 Protein,mFc Tag 94977ES25 25 μg 94977ES60 100 μg 94977ES76 500 μg Product Properties Synonyms CD94; CD159a; NKG2-A; Source Human NKG2A&CD94 Protein is expressed from HEK293 with mFc (IgG1) tag at the C-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 56.9 kDa. Due to glycosylation, the protein migrates to 70-90 kDa based on SDS-PAGE result. Endotoxin < 1EU per μg by the LAL method. Activity Blocking Data: Serial dilutions of Anti-NKG2A Antibody were added into Biotinylated Human HLA-E*01:03 Complex Tetramer, His Tag : Human NKG2A&CD94, mFc Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 0.15μg/ml. ELISA Data: Immobilized Human NKG2A&CD94, mFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-NKG2A Antibody, hFc Tag with the EC50 of 12.4ng/ml determined by ELISA. SPR Data: Human NKG2A&CD94, mFc Tag captured on CM5 Chip via Anti-mouse Antibody can bind Human HLA-E Complex Tetramer, His Tag with an affinity constant of 7.90 nM as determined in SPR assay . Purity > 95% as determined by SDS-PAGE and 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 The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3-6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. Note 1. Please operate with lab coats and disposable gloves,for your safety. 2. This product is for research use only.
