1VAPOR DIFFUSION, HANGING DROP4.7293Crystals grown at 0.17 M sodium citrate (pH 6) and 17-18% (w/v) PEG3350. Soaked for 1-2 minutes (empirically determined for each crystal) in equivalent solution with 0.025% (w/v) glutaraldehyde. Finally transferred and soaked for 10-20 sec in solution containing 40% (w/v) PEG3350, 5 mM L-L-Asp, and 0.17 M sodium citrate (pH 4.7)
