WebJan 1, 1974 · The pH optimum for the proteolytic action of trypsin is between 7.0 and 8.0. The substrate and tyrosine standard solution should be stored in a refrigerator at 0–4°C. The specific activity is defined as the number of trypsin units per mg protein nitrogen. 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).
