1	VAPOR DIFFUSION, HANGING DROP		277	The 1.4 mM apo-protein was prepared in 100 mM pH=5.6 NaOAc buffer. For each well, add 300 uL reservoir buffer containing 100 mM pH=8.0 Tris-HCl, 10 mM CuSO4 and 20% PEG-4000. 3 uL of protein stock was mixed with 1 uL reservoir buffer on the glass slides and sealed on the wells. Diamond-shaped blue crystals grew within 4 days.
