1	VAPOR DIFFUSION, HANGING DROP	5.6	298	DROPS CONTAINING 1.5 MICROLITERS 5 MG/ML PROTEIN IN 20 MM HEPES PH 7.0 WERE COMBINED WITH 1.5 MICROLITERS WELL SOLUTION (85 MM AMMONIUM ACETATE, 42 MM TRI-SODIUM CITRATE, 12.3% PEG 4000, 7.5% GLYCEROL, 15 MM L-CYSTEINE, 5 MM UDP-GLC) FOR 1-2 WEEKS. CRYSTAL WAS THEN SOAKED IN A SOLUTION OF 53% QIAGEN CRYOS SUITE CONDITION #87 WITH 15 MM L-CYS AND 23 MM FLAVIN MONONUCLEOTIDE (24HRS). CRYSTAL WAS BRIEFLY SOAKED (20 SECONDS) IN A SOLUTION OF 53% QIAGEN CRYOS SUITE CONDITION #87 WITH 15 MM L-CYS, 30% METHANOL, 10 MM FLAVIN MONONUCLEOTIDE PRIOR TO VITRIFICATION, VAPOR DIFFUSION, HANGING DROP, temperature 298K
