1VAPOR DIFFUSION, HANGING DROP6.5293Trypsin, final concentration of 0.6 mM, was dissolved in 20 mM HEPES pH 7.0, 10 mM calcium chloride, 3% DMSO, and 3 mM of ligand of interest (compounds 3, 6, and 9). The well solution consisted of 100 mM Cacodylate pH 6.5, 200 mM ammonium sulfate, 50% PEG (17% to 28%). The ligands were co crystallized with protein using vapor diffusion and hanging drop method. The drops were 1:1 (protein:well solution), VAPOR DIFFUSION, HANGING DROP, temperature 293K
