1	COUNTER-DIFFUSION	5.4	293.2	The mixture of protein solution and agarose was filled into a glass capillary, and the capillary was immersed in the reservoir solution for crystallization. The composition of the reservoir solution was as follows, 15%(v/v)PEG#200, 0.1M phosphate citrate pH5.4, 5mM MTA. Crystals soaked in 0.1M potassium phosphate pH7.0 with 5mM MTA.
