1	VAPOR DIFFUSION, HANGING DROP	7.5	277	The native PDE10A2 crystals were grown against a well buffer of 0.1 M HEPES (pH 7.5), 0.2 M MgCl2, 50 mM beta-mercaptoethanol(BME), and 16% PEG3350. The complex of PDE10A2-AMP was prepared by soaking the crystals in 20 mM cAMP, VAPOR DIFFUSION, HANGING DROP, temperature 277K
