Crystallization

Crystalization Experiments
ID	Method	pH	Temperature	Details
1	VAPOR DIFFUSION, HANGING DROP	6.5	291	Protein concentration 24 mg ml-1 in 50 mM sodium cacodylate buffer, pH 6.5, 2 mM CaCl2 and 100 mM NaCl. The enzyme was crystallised by hanging drop vapour diffusion in drops containing 1 microliter of protein and 1 microliter of reservoir solution over 0.5 ml of reservoir: Hampton Screen 2 no. 23 (10% dioxane, 0.1 M 2-(N-Morpholino)-ethanesulphonic acid (MES) buffer, pH 6.5, 1.6 M ammonium sulphate). Clusters of elongated plates appeared after several days.
