1				THE COMPLEX WAS CO-CRYSTALLIZED. THE CO-CRYSTALS WERE GROWN BY THE METHOD OF VAPOR DIFFUSION IN 40 MICROLITER DROPS CONTAINING 9MG(SLASH)ML OF ELASTASE, 0.1 MILLIMOLAR TFA-LYS-PRO-ISO, 1.4 MILLIMOLAR SODIUM SULFATE AND 100 MILLIMOLAR SODIUM ACETATE AT PH 5. THE RESERVOIR CONSISTED OF 100 MILLIMOLAR SODIUM SULFATE AND 100 MILLIMOLAR ACETATE BUFFER AT PH 5.
