The skin protease inhibitory factor of plasma

Abstract

M. HOLDEN I946 other groups. The influence of manurial treatment on pectase content will be reported in more detail later. DISCUSSION Lineweaver et al. made their activity determinations at 300 so that all the values given here have to be increased by 40 % to make them comparable with theirs. Their preparations with a specific activity of 2*5 units/mg. protein N have an activity about twice that of the most active preparations obtained in the present investigation. Adsorption on and elution from Celite did not result in such a large increase in specific activity as found by these workers, which may be due to the presence of a different type of impurity.
