THE RESERVOIR CONTAINED 20-25% AMMONIUM SULFATE, 30-60 MM DITHIOTHREITOL AND 100MM MORPHOLINOETHANESULFONIC ACID BUFFER PH5.4. DROPS WERE STREAK SEEDED AFTER 1 DAY USING A CAT'S WHISKER FROM CRYSTALS GROWN UNDER SIMILAR CONDITIONS. SOLID CIBACRON BLUE WAS SEEDED INTO THE DROP. SIX WEEKS LATER THE CRYSTALS WERE SUBJECTED TO X-RAY ANALYSIS., pH 6.0, vapor diffusion - hanging drop - streak seeding Resolution 2.45 Å R-free 0.280
