Recombinant SARS-CoV-2 Spike S1+S2 ECD(S-ECD) Protein (RP01260MT)

文献引用 (2) 说明书 收藏

Recombinant SARS-COV-2 S1+S2 ECD (S-ECD) Protein with His tag was determined by SDS-PAGE with Coomassie Blue, showing a band at 170-220 kDa.

The purity of SARS-COV-2 Spike S Trimer is greater than 95% as determined by SEC-HPLC.

Immobilized Recombinant SARS-COV-2 Spike S1+S2 ECD at 2μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-3.03 ng/mL.

Immobilized SARS-COV-2 Spike S Trimer, His Tag at 1μg/ml (100μl/Well). Dose response curve for Human ACE2, hFc Tag with the EC50 of 42.2ng/ml determined by ELISA.

描述
Recombinant SARS-CoV-2(2019-nCoV) S1+S2 ECD（S-ECD） Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence Val16-Glu1188 of SARS-COV-2(2019-nCoV) S1+S2 ECD（S-ECD） (Accession #QHD43416.1) fused with a 6×His tag at the C-terminus.
储存
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。
生物活性
Measured by its binding ability in a functional ELISA. Immobilized Recombinant SARS-CoV-2 Spike S1+S2 ECD at 2 μg/mL (100 μL/well) can bind Recombinant Human ACE2 with a linear range of 0.15-3.03 ng/mL.
复溶
Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。
