样本类型 重组蛋白

技术参数 表达系统HEK293 Cells 标签His tag at the C-terminal 外观冻干粉 内毒素水平< 1.0 EU per 1μg of the protein by the LAL method. 分子量Approximately 25.99 kDa. Due to glycosylation the protein migrates to 35-43 kDa based on Tris-Bis PAGE result. 制剂Lyophilized from 0.22μm filtered solution in PBS (pH 7.4) 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. 纯度> 95% as determined by SDS-PAGE and HPLC. 储存条件The product should be stored at -25~-15℃. 1 month 2 ~8 °C under sterile conditions after reconstitution. 3 months -25~-15℃ °C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles. 活性ELISA检测显示与人ACE2结合的EC50为27.0 ng/ml；浓度等详见生物活性描述。
