Crystals of bovine heart ubiquinol-cytochrome c reductase diffracting X-rays up to 2.8 Å resolution at 276 K

Bovine heart ubiquinol-cytochrome c reductase stabilized with sucrose monocaplate was crystallized with polyethylene glycol as the precipitant at 277 K. X-rays diffracted by the crystal were detected up to 2.8 Å resolution at 266 K, without using a synchrotron source. The space group and cell dimensions are P6₁ or P6₅ and a = b = 128.5 and c = 715.7 Å, respectively.
