技术平台 HEK293细胞表达

应用方法 新冠研究研究Spike RBD与ACE2受体的相互作用

适用物种种属 SARS-CoV-2

检测方法 ELISA SDS-PAGE SEC-HPLC LAL

生物特性参数 蛋白类型重组生物素化SARS-CoV-2 Spike RBD蛋白 种属来源SARS-CoV-2 生物活性描述与Human ACE2结合，EC50为27.2ng/ml（ELISA） 应用研究Spike RBD与ACE2受体的相互作用

技术参数纯度> 95% as determined by SDS-PAGE and SEC-HPLC 内毒素水平Less than 1 EU per μg by the LAL method. 分子量Predicted MW 51.7 kDa; migrates to 60-62 kDa by Bis-Tris PAGE due to glycosylation 制剂形式Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. 活性EC50 of 27.2ng/ml determined by ELISA for binding to Human ACE2 储存条件-25~-15℃保存，有效期1年；复溶后-85~-65℃保存，3个月；避免反复冻融 表达系统HEK293 标签C-hFc-Avi 表达序列Arg319-Asn532 AccessionQHD43416.1 外观Lyophilized Powder 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。
