1VAPOR DIFFUSION, SITTING DROP7.5289The enzyme (8.6 mg/mL) in 50 mM HEPES pH 7.8, 150 mM KCl, 1 M L-proline, and 1 mM ZnCl2 was mixed in a 1:1 ratio with 25 % (w/v) pentaerythritol propoxylate (17/8 PO/OH), 100 mM HEPES pH 7.5. The final size of the drops was 1 microliter. Prior to flash freezing the crystals in liquid nitrogen, the mother liquor was supplemented with 37 % (w/v) pentaerythrol propoxylate (17/8 PO/OH).
