Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1AOS SUCROSE PORIN (PDB ENTRY 1AOS)
Crystallization Crystalization Experiments ID Method pH Temperature Details 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%. 2M SUCROSE WAS ADDED TO THE DROP FOR COCRYSTALLIZATION., vapor diffusion - sitting drop
