检测方法 ELISA SPR SDS-PAGE LAL

生物特性参数 蛋白类型Spike S1 protein 种属来源SARS-CoV-2 生物活性描述EC50 of 59.7ng/ml for binding to Human ACE2 by ELISA; affinity constant of 0.132 μM to Human ASGR1 by SPR 应用ELISA Data : Immobilized Human ACE2 His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for SARS-COV-2 Spike S1 hFc Tag with the EC50 of 59.7ng/ml determined by ELISA .SPR Data: Biotinylated Human ASGR1 His Tag captured on CM5 Chip via Anti-his antibody can bind SARS-COV-2 Spike S1 hFc Tag with an affinity constant of 0.132 μM as determined in SPR assay .

技术参数纯度> 95% as determined by SDS-PAGE 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 101.6 kDa. Due to glycosylation the protein migrates to 115-130 kDa based on Bis-Tris PAGE result. 制剂形式Supplied as 0.22μm filtered solution in PBS (pH 7.4) 储存条件-85~-65℃保存，收到货之日起，有效期1年。建议分装蛋白为一次实验使用量，分装后，-80℃冻存。避免反复冻融。 表达系统HEK293 标签C-hFc 外观Liquid 表达序列Val16-Arg685 登录号QHO60594.1 产品别称S1 protein;Spike protein S1;Spike S1 protein;S glycoprotein Subunit1
