MES 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. Crystals
Transferred In Reservoir Solutions Whose Ph Was Increased
From 6.0 To 8.0 By Steps Of 0.5 Ph Units (The Soaking Time
In Each Solution Was 12 Hours). Manganese Derivative Was
Obtained By Soaking For 24 Hours Protein Crystals In The
Reservoir Solution Supplemented With 10 Mm MnCl2 (PH 8.00).
Crystals Were Frozen In Liquid Propane After Soaking For A
Few Seconds In Peg MME 550 (50%), Tris PH 8.0 (40 Mm)., VAPOR DIFFUSION, HANGING OR SITTING-DROP |
