1VAPOR DIFFUSION, HANGING OR SITTING-DROP6285MES 50mM PH6.0, PEG MME 550 32% AT 285K. The Protein Was Concentrated at 2 MG/ML In MES-NAOH PH 6.00 (20 mM), DTT (5 mM) And Mixed With An Equal Volume Of The Reservoir Solution Containing PEG MME 550 (32%), MES PH 6.00 (40 mM), DTT (5 mM). Crystal Size (300X40X40 microM3) In 20microL Sitting Drops. Manganese Derivative Was Obtained By Soaking For 24 Hours. Protein Crystals In The Reservoir Solution Were Supplemented With 20 Mm MnCl2 (PH 6.00).Crystals Were Frozen In Liquid Propane After Soaking For A Few Seconds In PEG MME 550 (50%), MES PH 6.00 (40 mM)., VAPOR DIFFUSION, HANGING OR SITTING-DROP
