Pmsf shelf life
Web• Use materials and containers appropriate for PMSF use and remain aware of potential incompatibilities; PMSF is incompatible with water, acids, bases, and strong oxidizing agents. Do not store PMSF in glass or mild steel/galvanized containers. Store in a cool, dry, and well-ventilated area away from incompatible chemicals. WebMay 14, 2024 · Like with refrigerated tofu, shelf-stable tofu should have an expiration date. Check the expiration date to find out how long a particular package of tofu will last. If you find a package that doesn't have one, simply move on to another one. In general, shelf-stable tofu will last for 6 months to a year from the date of production.

WebPMSF (phenylmethylsulfonyl fluoride) is an irreversible serine protease inhibitor used in various research and lab settings. The compound has a white powdery appearance at room temperature, with a melting point between 90-95°C. It functions by inhibiting serine proteases such as trypsin, chymotrypsin, and thrombin, and cysteine proteases like papain.
