1VAPOR DIFFUSION3.1CRYSTALS WITH DIMENSIONS 0.25X0.25X0.25 MM3 WERE OBTAINED AT ROOM TEMPERATURE BY VAPOUR DIFFUSION AGAINST A RESERVOIR CONTAINING 0.1 M CITRIC ACID PH 3.1, 2 M AMMONIUM SULPHATE, 0.2 M SODIUM CHLORIDE, AND 1MM DTT/EDTA. THE HANGING DROP CONTAINED 1:1 RATIO OF RESERVOIR AND PROTEIN-PEPTIDE SOLUTIONS., vapor diffusion
