1 | VAPOR DIFFUSION, HANGING DROP | 4.5 | 294 | Tetragonal crystals were grown by the vapour-diffusion technique using the hanging-drop method, with 0.7-1.0 M sodium chloride and 50 mM sodium acetate buffer at pH 4.5. Derivative crystals containing gadolinium were obtained using concentrations of Gd-HPDO3A in the range 10-100 mM. |
