1	BATCH MODE		295	20 mg/ml protein in 25 mM HEPES pH 7.5, 500 mM NaCl, 0.5 mM TCEP was mixed 1:1.5 with precipitant solution (0.1 M HEPES 6.5, 0.2M ammonium acetate, 20% PEG 3350, 50mM sodium/potassium tartrate, 0.8mM quercetin). Batch grown crystals were subsequently mixed 1:1 with 100 mM ATP/50mM magnesium chloride in DRAK2 crystallization buffer and incubated for half an hour.
