1 | VAPOR DIFFUSION, SITTING DROP | 7.7 | PROTEIN WAS CRYSTALLIZED BY VAPOR DIFFUSION USING THE SITTING-DROP METHOD. THE DROP CONTAINED 5-7 MG/ML PROTEIN, 20 MM TRIS/CL AT PH 7.7, 100MM LICL, 20MM MGSO4, 1.2% BETA-D-OCTYLGLUCOPYRANOSIDE AND 6-9% PEG-2000. THE CONCENTRATION OF PEG IN THE RESERVOIR WAS 12-15%., vapor diffusion - sitting drop |
