Figure 8. (A) Zymogram analysis of the effect of some proteinase inhibitors on BApNA hydrolytic activity of salivary gland extract (MWM: molecular weight markers, Control: no inhibitor, PMSF: 1 mM, TLCK: 0.1 mM, TPCK: 0.1 mM and E-64: 10 μM). (B) Zymogram analysis of hydrolytic activity of the salivary gland extract on the substrate APNE (MWM: molecular weight markers in kDa, P: bands with proteolytic activity).
