WebBlank: 500 µL BApNA usage solution and 500 µL buffer. Control: 100 μL trypsin solution and 400 μL buffer. Test: 100 µL enzyme, 100 µL leaf extract (source of inhibitors) and 300 µL buffer. 3 Mix the three microtubes by inversion and equilibrate to 25°C for 5 min Zero spectrophotometer with blank content at 410 nm Web.activity toward BApNA, led us to the careful examination of trypsin-catalyzed hydrolysis of this substrate. The study was done by using L-BApNA which was recently synthesized by Nishi et al. (11). As this optically active compound has a high solubility compared with the conventional racemate (12), the reaction Webas substrate for their analysis. Trypsin was inhibited by specific trypsin inhibitor N α-p-tosyl-L-lysine chloromethyl Ketone (TLCK) and specific proteolytic activity of Bromelain was analysed using Whey protein. Bromelain was inactive towards N-a-benzoyl-DL-arginine p-nitroaniline (BApNA) therefore; BApNA was used trump university lawsuit facts
