Recombinant Cynomolgus PD-L1/B7-H1 Protein,hFc Tag

Description :
Synonyms PD-L1; PDL1;CD274;B7-H Source Cynomolgus PD-L1/B7-H1 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Phe19-Arg238.[Accession | G7PSE7] Molecular Weight The protein has a predicted MW of 52 kDa. Due to glycosylation, the protein migrates to 60-70 kDa 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 ELISA Data: Immobilized Cynomolgus PD-L1, hFc Tag at 1g/ml (100l/well) on the plate. Dose response curve for Biotinylated Anti-PD-L1 Antibody, hFc Tag with the EC50 of 10.0ng/ml determined by ELISA. 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.
