Take it 30 minutes before a meal or as directed by your doctor. Stop using Trypsin Chymotrypsin at least 2 weeks before a scheduled surgery as it may interfere with blood clotting. Inform your doctor if you have liver or kidney disease or problems with your blood clotting mechanism.
Trypsin is a serine protease that specifically cleaves at the carboxyl side of lysine and arginine residues. The selectivity of this enzyme is critical for reproducible protein digestion and mass spectrometry-based protein identification. Since chymotrypsin co-purifies with trypsin derived from natural sources, Pierce Trypsin Protease has been treated with TPCK to eliminate chymotryptic activity, improving digestion specificity. Native trypsin is also subject to autolysis which can reduce enzyme stability and efficiency. To reduce autolytic degradation, Pierce Trypsin Protease is chemically modified by methylation, yielding a highly active and more stable form of the enzyme.

Trypsin from the pyloric caeca of bigeye snapper was purified and characterized. Trypsin had an apparent molecular weight of 23.8 kDa when analyzed using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and substrate-gel electrophoresis. The trypsin fraction consisted of three isoforms as evidenced by the appearance of three different bands on native-PAGE. Optimal activity was observed at 55C and pH range of 8–11.
