… These solutions were prepared with 50 mM HEPES buffer with a pH of 7.4, on a 96-well plate, separately before being combined to result in final concentrations of 30 µM inhibitor, 150 nM enzyme, and 9 µM substrate (SNAPtide, List laboratories). An excitation wavelength of 490 nm was used and an emission at 523nm was observed and recorded for 5 mins. Two controls run were performed at the same time, containing no inhibitor. …
