1	VAPOR DIFFUSION, HANGING DROP	8.5	298	Ligand in lyophilized powder form was dissolved in a 9.5 mg/mL solution of Grb2 SH2 in water such to give a protein/ligand molar ratio of 2:1. 4uL of this solution was mixed with 3uL of 0.1 M MgCl2 x 6H2O, 30% w/v PEG MW4000, 0.1 M TRIS, pH 8.5 to create the hanging drop, which yielded crystals of the protein-ligand complex in the presence of the above-mentioned solution after four weeks at room temperature., VAPOR DIFFUSION, HANGING DROP, temperature 298K
