1	MICROBATCH	6.5	292	Precipitant solution was 16-20% PEG 8K in 0.1M pH 6.5 Hepes buffer, 50 mM CaCl2 with microseeding. Crystals were soaked in 0.1M Hepes 7.4, 20% PEG 8K, 25% glycerol 0.5 mM ligand prior to passage through paratone and freezing. Crystals grew as large doubly birefringent rods which were gently crushed. Singly birefringent pieces were selected for data collection.
