1	VAPOR DIFFUSION, SITTING DROP		293	Equivolumetric drops consisting of 0.2M tribasic ammonium citrate, pH6.4, 15% (w/v) polyethylene glycol 3350, plus 0.05M sodium fluoride as an additive, and protein solution at 4.9 absorption units at lambda=280nm yielded a single large well-shaped monocrystal after several months. This crystal could not be reproduced despite extensive trials.
