Anti-tryptic and proteolytic activity of NMR and human plasma.

<p>The inactivation of 0.05 μg trypsin was titrated with increasing amounts of human (A) or NMR (B) plasma corresponding to 1–100 μg protein and measured by the conversion of BAPNA to p-nitroaniline at 405 nm. The intrinsic tryptic activity of NMR and human plasma was determined by measuring the conversion of BAPNA to p-nitroaniline induced by 1–100 μg plasma protein (C). (*—p<0.05)
