The crystal was transferred to a hanging drop containing 0.1M Tris pH 7, 75mM MaCl, 0.2M MgCl2, and 20% PEG800, which was then placed over a vapor diffusion chamber containing a sitting drop bridge with 25% glutaraldehyde. The crystal was cross-linked for 8 minutes at room temperature, then transferred to a soaking solution containing 0.1M Tris pH 7, 75mM NaCl, 0.2M MgCl2,20% PEG8000, 11.6mM trimethyl lead acetate, and 9.63mM triethyl lead acetate for 43 hrs at room temperature. The soaked crystal was then transferred to a cryoprotectant (0.1M Tris pH 7, 75mM NaCl, 0.2M MgCl2, 20% PEG8000, 15% ethylene glycol, 11.9mM trimethyl lead acetate, and 13.75mM triethyl lead acetate) in four steps, then flash frozen in liquid nitrogen. , VAPOR DIFFUSION, SITTING DROP, temperature 297K
