1	VAPOR DIFFUSION, HANGING DROP	5.6	298	Ligand in lyohpilized power form was dissolved in a 10.0 mg/mL solution of Grb2 SH2 in water such to give a protein/ligand molar ratio of 1:2. 3.5 uL of this solution was mixed with 3.5 uL of 20% v/v isopropanol, 20% w/v polyethylene glycol MW 4,000, 0.1 M sodium citrate dihydrate, pH 5.6 to create the hanging drop, which yielded crystals of the protein-ligand complex after two weeks, VAPOR DIFFUSION, HANGING DROP, temperature 298KK
