The protein solution consisted of 6.0 mg/ml MR purified as described above, 50mM HEPES buffer (pH 7.5), and 3.3 mM MgCl2. 20mM of 3-HP was added to the protein solution before being mixed with the batch reservoir. The protein solution and reservoir solution were gently mixed in a 1:1 ratio. The mixture was pipetted into a lightly greased well to prevent the crystals from adhering to the well bottom and sealed with a glass coverslip lined with mineral oil. The spontaneous crystals grew for 17 hours, resulting in hexagonal prism and octahedral shaped crystals, and were looped directly from the wells to be flash-cooled in liquid nitrogen for storage.
