Sample preparation
Crystal | Density Matthews: 2.17 Å3/Da / Density % sol: 43.39 % Description: Tetragonal shaped crystals amenable to diffraction studies were grown by the hanging drop vapor diffusion method on silanized glass covers slips at 20 C and grew with dimensions ...Description: Tetragonal shaped crystals amenable to diffraction studies were grown by the hanging drop vapor diffusion method on silanized glass covers slips at 20 C and grew with dimensions routinely exceeding 0.1 x 0.1 x 0.5mm. Gd3+, a competitive inhibitor of Mg2+, has a useful anomalous absorption edge at the CuK wavelength and therefore was used in the co-crystallization or soaking conditions. |

Upon reaching maximum size after ~5 days, a Gd3+ heavy atom derivative was prepared by adding 0.5uL of 17.5mM Gd2(SO4)3 in reservoir solution to 3uL hanging drops (2.5mM final Gd3+) containing native crystals for 48 hours |
