1	VAPOR DIFFUSION, SITTING DROP	7.8	295	Crystals of thecomplex between FGF-1 and 2,5-DHPS (2,5-dihydroxyphenylsulfonate) were grown using the sitting drop vapour method at 295 K. Equal volumes of protein and inhibitor solutions, 0.75 and 1.5mM, respectively were mixed with drops containing 60% sodium/potassium tartrate buffered with 5mM sodium phosphate [pH 7.8]. The drops were equilibrated against 0.2ml of 1.3M Li2SO4 and typical crystals grew within two weeks with approximate dimensions of 0.7 x 0.5 x 0.2 mm. , VAPOR DIFFUSION, SITTING DROP
