1	VAPOR DIFFUSION, HANGING DROP		298	A 4uL hanging drop comprising: 2uL 14 mg/mL R15L hGSTA1-1 solution added to 2uL reservoir buffer (5mM S-hexyl-glutathione, 0.1M TrisHCl, pH 7.5, 10 mM DTT, 15% PEG 4000) was left to equilibrate in a sealed 24 plate well with 1 mL of reservoir buffer. Crystals were grown for 3 days before harvesting, VAPOR DIFFUSION, HANGING DROP, temperature 298K
