ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	8.5	298	Ligand in lyophilized powder form was dissolved in a 7.2 mg/mL solution of Grb2 SH2 in water such to give a protein/ligand molar ratio of 1:1.7. 4 uL of this solution was mixed with 3 uL of 12% v/v glycerol, 1.5 M ammonium sulfate, 0.1 M TRIS, pH 8.5 to create the hanging drop, which yielded crystals of the protein-ligand complex after 8 weeks, VAPOR DIFFUSION, HANGING DROP, temperature 298K
