性能参数

分子别名（Synonyms）	ErbB2; EGFR2;CD340; HER-2
表达区间及表达系统（Source）	Human Her2/ErbB2 Domain 4 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Pro489-Cys630.[Accession \| P04626-1]
分子量大小（Molecular Weight）	The protein has a predicted MW of 18.5 kDa. Due to glycosylation, the protein migrates to 28-40 kDa based on SDS-PAGE result.
内毒素（Endotoxin）	Less than 1EU per μg by the LAL method.
纯度（Purity）	> 95% as determined by SDS-PAGE and HPLC.
活性（Activity）	ELISA Data: Immobilized Human Her2 Domain 4, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Anti-Her2 Antibody, hFc Tag with the EC50 of 13.1ng/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.
