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). WebOur in vitro studies also indicated that trypsin was denatured slowly between pH 6 and 4.25 and rapidly between 4.25 and 3.75. The rate of denaturation was faster at room temperature and slower in ice over a broad range of pHs. In our in vivo studies, hypersecretors showed tryptic activities consistently lower than normosecretors.
