Recombinant Mouse IL-9 Protein,His Tag 重组小鼠白介素9

Description :
别名Synonyms Interleukin-9; IL-9; Cytokine P40; T-cell growth factor P40; HP40; P40 Source Mouse IL-9Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Gln19-Pro144.[Accession |P15247] Molecular Weight The protein has a predicted MW of 15.4 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin by the LAL method. Purity > 95% Tris-Bis PAGE和 HPLC检测 生物Biological Activity Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50for this effect is 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
