Recombinant Human Periostin/OSF-2 Protein,His Tag

Description :
Source Human Periostin/OSF-2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asn22-Gln836.[Accession |Q15063] Molecular Weight The protein has a predicted MW of 92.1 kDa. Due to glycosylation, the protein migrates to 93-100 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGEandHPLC Activity ELISA Data:Immobilized Human Periostin, His Tag at 0.5g/ml (100l/well) on the plate. Dose response curve for Anti-Periostin Antibody, hFc Tag with the EC50 of 18.5ng/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.
