1	VAPOR DIFFUSION, HANGING DROP	8	292	Crystals of the Fab/HER2 complex were obtained by mixing protein solution (11 mg/ml protein, 25 mM Tris-HCl pH 8 and 150 mM sodium chloride) with crystallization buffer containing 25% w/v PEG2000, 0.1M MES pH 6.5. Before data collection the crystals were flash frozen in liquid nitrogen with 20% Ethylene Glycol as cryo-protectant, pH 8.0, VAPOR DIFFUSION, HANGING DROP, temperature 292K
