性能参数
表达区间及表达系统（Source） | Human Periostin/OSF-2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asn22-Gln836.[Accession | Q15063] |
分子量大小（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 μg by the LAL method. |
纯度（Purity） | > 95% as determined by Tris-Bis PAGE and HPLC |
活性（Activity） | ELISA Data: Immobilized Human Periostin, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-Periostin Antibody, hFc Tag with the EC50 of 18.5ng/ml determined by ELISA. |
制剂（Formulation） | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
重构方法（Reconstitution） | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
