1		7		TWO SLIGHTLY DIFFERENT CRYSTAL FORMS OF FAB 5G9 WERE OBTAINED USING 17.5% PEG 10K AT PH 8.5 AND 1.35M SODIUM CITRATE AT PH 5.5 AS PRECIPITANTS. THE TWO CRYSTAL FORMS ARE BOTH ORTHORHOMBIC, P212121, WITH TYPICAL SIZES OF 0.5 X 0.4 X 0.3 MM3 (CITRATE FORM) AND 0.6 X 0.35 X 0.2 MM3 (PEG FORM), WITH SLIGHTLY DIFFERENT CELL PARAMETERS OF A=89.1A, B=90.5A, C=59.3A (CITRATE) AND A=91.6A, B=93.7A, C=60.7A (PEG). PEG FORM IS USED FOR STRUCTURE DETERMINATION., pH 7.0
