Upon receipt, please store all items at -70℃. After reconstitution, the stock solution should be kept at -70℃.
It is recommended not to freeze thaw more than 3 times.
No activity loss is observed after storage at: Room temperature (RT) for 1 month in lyophilized state; -20℃ for 1 year in lyophilized state; -70℃ for 6 months under sterile conditions after reconstitution.
Your experiment will include 4 simple steps:
a) Coat the plate with SARS-CoV-2 S protein RBD.
b) Add 50ul biotinylated human ACE2 to coated plate.
c) Add the reference in kit or your samples in serum or plasma of interest.
d) Add Streptavidin-HRP followed by TMB or other colorimetric HRP substrate.
Finally, the titer of your samples to inhibit S protein RBD: ACE2 binding will be determined by comparing OD readings among different experimental groups.
