Immobilized SARS-CoV-2-S1-RBD at 2 μg/ml can bind SARS-CoV-2-S Antibody (CSB-RA33245A1GMY), the EC50 of SARS-CoV-2-S1-RBD protein is 19.60-39.42 ng/ml.②Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 5 μg/ml can bind human ACE2 (CSB-MP866317HU), the EC50 of SARS-CoV-2-S1-RBD protein is 31.80 - 44.69 ng/ml.③Measured by its binding ability in a functional ELISA. Immobilized SARS-CoV-2-S1-RBD at 2 μg/ml can bind SARS-CoV-2-S Antibody (CSB-RA33245A0GMY), the EC50 of SARS-CoV-2-S1-RBD protein is 13.48-19.50 ng/ml.
||Human Novel Coronavirus (SARS-CoV-2/ 2019-nCoV)
|Target Protein Sequence
|| N-terminal 6xHis-sumostar-tagged
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
|| If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
||We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
||Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
||The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
||Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
||Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
