Specifications Source Biotinylated Human NKG2A&CD94 Protein is expressed from HEK293 with His tag and Avi tag at the N-terminal. 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 Less than 1EU per μg by the LAL method. Purity > 95% as determined by Tris-Bis PAGE and HPLC Activity ELISA Data: Immobilized Anti-NKG2A Antibody, hFc Tag at 1μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Human NKG2A&CD94, His Tag with the EC50 of 0.11μg/ml determined by ELISA. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes 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 the date of receipt. 2-7 days, 2 ~8 °C under sterile conditions after reconstitution. 3 months, -25~-15℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
