1	BATCH MODE	3.5	274	Crystals with sizes between 6 and 8 um in diameter were obtained by adding three parts of precipitant (1M NaCl, 40% ethylene glycol (v/v), 15% PEG4000 (w/v), 50 mM acetate buffer at pH 3.5, filtered through 450 nm filter) to one part of lysozyme (Sigma-Aldrich, 126 mg/ml dissolved in50 mM acetate buffer, pH 3.5, filtered through 100 nm filter) at 274K (ThermoStat C, Eppendorf, Germany). The resulting mixture was immediately subjected to rapid mixing and incubated for 30 minutes at 274K.
