            表達區(qū)間及表達系統(tǒng)(Source)

            Ferret TNF alpha Protein is expressed from E.coli without tag. It contains Val77-Leu233.[Accession | A3FBF1]

            分子量大?。∕olecular Weight)

            The protein has a predicted MW of 17.21 kDa same as SDS-PAGE result.

            內(nèi)毒素(Endotoxin)

            Less than 1EU per μg by the LAL method.

            純度(Purity)

            > 95% as determined by SDS-PAGE and HPLC.

            活性(Activity)

            ELISA Data: Immobilized Ferret TNF-alpha, No Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human TNFR2, hFc Tag with the EC50 of 14.5ng/ml determined by ELISA.

            制劑(Formulation)

            Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

            重構方法(Reconstitution)

            Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
