BAPNA hydrolysis activity (as an indicator of protease activity) in the presence and absence of S-PRG eluate. P.-gingivalis-sonicated extract was added to the reaction mixture. To analyze the effect of S-PRG, distilled water in control mixture (triangle) was replaced with S-PRG solution (circle). Colored metabolites were quantified using a colorimetric absorbance assay at 405 nm. Data are representative of three independent experiments and the bars indicate the standard deviation.
