1VAPOR DIFFUSION, SITTING DROP277Crystals appeared after two weeks when mixed 1:1 ratio with mother liquor containing sodium phosphate monobasic (1.26M to 1.61M) and potassium phosphate dibasic (0.14M to 0.24M). Ligand was soaked for at least 1 hour at a final concentration between 10-50 mM (10% DMSO).
