Abstract
TRYPSIN inhibitors have been found in pancreas, serum, colostrum, egg-white, soya bean, and lima bean1. They have all been crystallized except from egg-white2. Thus, examination of the distribution of trypsin inhibitors in proteins of them appears to be out of the question. Recently, Nakamura et al.3 have demonstrated, by two-dimensional paper electrophoresis, that two trypsin inhibitors were contained in the extract of soya-bean. Hence the distribution of trypsin inhibitors in other biological fluids deserves to be re-investigated to see whether there are also two inhibitors in them or not.
