WebTrypsin Gold, Mass Spectrometry Grade, has extremely high specific activity. Modified trypsin is maximally active in the range of pH 7–9 and is reversibly inactivated at pH <4. It is resistant to mild denaturing conditions such as 0.1% SDS, 1M urea or 10% acetonitrile (3) and retains 50% of its activity in 2M guanidine HCl (4). 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). chimney lakes owners associationWebJan 1, 1974 · The pH optimum for the proteolytic action of trypsin is between 7.0 and 8.0.
