样本类型 重组蛋白

技术参数纯度> 95% as determined by SDS-PAGE and HPLC 内毒素水平< 1.0 EU per 1μg of the protein by the LAL method 分子量Approximately 26.05 kDa. Due to glycosylation the protein migrates to 35-45 kDa based on Tris-Bis PAGE result. 制剂形式Lyophilized from 0.22μm filtered solution in PBS (pH 7.4) 活性EC50 of 39.7ng/ml determined by ELISA 表达系统Expi293 标签His tag at the C-terminal 表达区间Arg319-Phe541(G339D S371F S373P S375F T376A D405N R408S K417N N440K L452R S477N T478K E484A F486V Q498R N501Y Y505H) 复溶方法Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
