1	VAPOR DIFFUSION, HANGING DROP	6.5	293	The VIIa/sTF complex was crystallized using the sitting drop or the hanging drop vapor diffusion method. Specifically, the protein drop contained 4 mg/ml VIIa/sTF complex, 20 mm Tris-HCl, pH 7.5, 200 mm NaCl, 10 mm CaCl2, and 10 mm pAB or 10 mm benzamidine, whereas the reservoir solution contained 16-22% PEG 4000, 100 mm MgCl2, and 20 mm BisTris, pH 6.5. Drops were prepared by mixing 2 ul of protein solution with 2 ul of reservoir solution at 20 C. Crystals appeared within 7 days and were allowed to grow up to 14-20 days before being flash-frozen without additional cryoprotectant.
