适用物种种属 SARS-CoV-2

检测方法 SDS-PAGE SEC-HPLC LAL ELISA

生物特性参数 种属来源SARS-CoV-2 生物活性描述ELISA Data 1:Immobilized SARS-CoV-2 Spike S1 (Lambda C.37) His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human ACE2 hFc Tag with the EC50 of 21.8ng/ml determined by ELISA.

技术参数 内毒素水平Less than 1 EU per μg by the LAL method. 分子量The protein has a predicted MW of 75.28 kDa. Due to glycosylation the protein migrates to 100-120 kDa based on Bis-Tris PAGE result. 表达序列Gln14-Arg683(G75V T76I R246N 247-253 del L452Q F490S D614G) 制剂形式Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. 复溶方法用蒸馏水溶解冻干的蛋白。如果规格为25μg或者100μg，建议复溶到0.5mg/mL的浓度。对于500μg或1mg的冻干粉，建议以1mg/mL的浓度复溶。复溶过程中请不要剧烈涡旋或者剧烈摇晃。将复溶后的蛋白溶液按照需求进行分装，储存于至-80℃，避免反复冻融。 数据库编号QHD43416.1 纯度> 95% as determined by SDS-PAGE and SEC-HPLC 表达系统HEK293 标签C-His 外观Lyophilized Powder 储存条件-25~-15℃保存，收到货之日起，有效期1年。复溶后， -85~-65℃保存，3个月有效期。避免反复冻融。
