Product Information
Description: VR23 is a small molecule that potently inhibited the activities of trypsin-like proteasomes (IC50 = 1 nM), chymotrypsin-like proteasomes (IC50 = 50-100 nM), and caspase-like proteasomes (IC50 = 3 μM).
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials at -20°C or below and used within 1 month.
