Laboratory Procedure

For long term storageㄛwe suggest
that Resveratrol be supplied at-20˚CㄝIt will be stable
for at least three year.
Resveratrol is supplied as a crystalline solid.A
stock solution may be made by dissolving the Resveratrol
in an
organic solvent purged with an inert
gas.Resveratrol is soluble in organic solvents such as
ethanol,DMSO,and dimethyl
formamide.The solubility of Resveratrol in these
solvents is at least 65mg/ml
Further dilutions of the stock
solution into aqueous buffers or isotonic saline should be
made prior to performing
biological experiments.Ensure that the residual
amount of organic solvent is insignificant,since organic
solvents may
have physiological effects at low
concentrations.Organic solvent-free aqueous solutions of
Resveratrol can be prepared
than 100ug/ml.We do not recommend storing the
aqueous solution for more than one day.
Resveratrol is a selective
inhibitor of cyclooxygenase-1(COX-1).¹ It inhibits
cyclooxgenase and peroxidase

3.7uM,respectively.respectively.It also has antioxidant
