WebThe acidic reconstituted solution (pH 3.0) can be stored at 2–8 °C for 2 weeks or at –20 °C for up to 4 weeks. The ammonium bicarbonate trypsin solution prepared for in-gel digests may be stored either at 2–8 °C for up to 2 weeks or as frozen aliquots for up to 4 weeks. Either trypsin solution is stable for at least 3 freeze-thaw cycles. Human trypsin has an optimal operating temperature of about 37 °C. In contrast, the Atlantic cod has several types of trypsins for the poikilotherm fish to survive at different body temperatures. Cod trypsins include trypsin I with an activity range of 4 to 65 °C (40 to 150 °F) and maximal activity at 55 °C (130 °F), as well as trypsin Y with a range of 2 to 30 °C (36 to 86 °F) and a maximal activity at 21 °C (70 °F).
