性能參數(shù)

分子別名（Synonyms）	HSIL5R3; CDw125CD125;CD125; IL-5R subunit alpha
表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）	Human IL-5 R alpha/CD125 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Asp21-Glu335.[Accession \| Q01344-1]
分子量大小（Molecular Weight）	The protein has a predicted MW of 62.6 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on 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 Human IL-5, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-5 R alpha, hFc Tag with the EC50 of 6.9ng/ml determined by ELISA.
制劑（Formulation）	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
重構(gòu)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.
