Recombinant Human EPO

Description :
别名Synonyms Erythropoietin, Epoetin Source Human EPOProtein is expressed from HEK293 without tag. It contains Ala28-Arg193.[Accession | AAH93628.1] Molecular Weight The protein has a predicted MW of 18.39 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin by the LAL method. Purity > 95% as determined by Tris-Bis PAGEand HPLC 生物Biological Activity Cell Based AssayMeasured in a cell proliferation assay using TF_x005f_x001e_1 human erythroleukemic cells. The ED50for this effect is 0.4 1 ng/mL Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. 外观Physical Appearance 白色冻干粉
