1	LIQUID DIFFUSION		298	Co-crystallized with LTA4H by liquid-liquid diffusion in melting-point capillaries. A Tris-buffered (10 mM, pH 7.5) solution of protein and inhibitor in approximately equimolar concentrations (~70 microM) was layered on the precipitate solution containing 28% (weight/volume) polyethylene glycol (Mw 8000), 50 mM Na acetate, 100 mM imidazole, pH 6.8, and 5 mM YbCl3, LIQUID DIFFUSION, temperature 298K
