The temperature and pH stabilities of Pnserpin. (a) Effects of temperature on the activity of Pnserpin. The inhibitor was incubated at the indicated temperature for 15 min, and the residual inhibitory activities against CHT (red open circle), SUC (blue open triangle), elastase (black solid circle), and PRK (green solid triangle) were measured; (b) Effects of pH on the activity of Pnserpin. The inhibitor was incubated at the indicated pH for 24 h at room temperature, and the residual inhibitory activities against CHT (red open circle), SUC (blue open triangle), elastase (black solid circle), and PRK (green solid triangle) were measured.
