性能參數

分子別名（Synonyms）	Activin RIIB;ACVR2B;Activin receptor type-2B
表達區間及表達系統（Source）	Human Activin RIIB/ACVR2B Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ser19-Thr137.[Accession \| Q13705-1]
分子量大小（Molecular Weight）	The protein has a predicted MW of 14.75 kDa. Due to glycosylation, the protein migrates to 25-45 kDa based on SDS-PAGE result.
內毒素（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 Human Activin A, No Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human Activin RIIB, His Tag with the EC50 of 21.4ng/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.
