ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	291	SAH and inhibitor were added to PRMT1 to a final concentration of 1.5mM each (3% DMSO). The complex was incubated at 4deg C before crystallization. 1uL protein-ligand complex was mixed with 1 uL of reservoir solution containing 0.3M sodium formate, 0.1M HEPES, 8% PEG 10,000, pH 6.5, and 0.2 uL 30% sodium dextran sulfate Mr=5,000). The droplets were incubated against 500uL reservoir solution for 1-2 days before crystals were observed.
