1	VAPOR DIFFUSION, SITTING DROP	7.5		HSCKALPHA1 AT 20 MG/ML WAS PREINCUBATED AT ROOM TEMPERATURE WITH 12 MM OF COMPOUND BR25 IN BUFFER 25 MM TRIS/HCL, 150 MM NACL PH 7.5 (DMSO IS AT 5% FINAL CONCENTRATION IN THE MIX). THE SITTING-DROP VAPOUR DIFFUSION METHOD WAS USED TO PRODUCE CRYSTALS BY MIXING 0.5 MICROL OF THE PROTEIN SOLUTION AND AN EQUAL VOLUME OF MOTHER LIQUOR (20% PEG 5000 MME AND 0.2 M KSCN). TETRAGONAL CRYSTALS (SPACE GROUP P43212) GREW WITHIN 2-4 DAYS AND THEN WERE SOAKED FOR ONE DAY WITH 20 MM COMPOUND BR25 SOLVED IN 100% DMSO. THE CRYSTALS USED IN THIS STUDY WERE CRYOPROTECTED IN MOTHER LIQUOR SOLUTIONS CONTAINING 20 % ETHYLENGLYCOL AND FROZEN IN A NITROGEN GAS STREAM COOLED TO 100 K.
