WebMar 5, 2015 · The cryoannealing protocol has been described. 6, 21 It involves multiple steps in which a freeze-quenched sample at liquid nitrogen temperature is rapidly warmed to the annealing temperature by immersion in a methanol bath held at that temperature, annealed at that temperature for a fixed time, then quench-cooled back to 77 K by … WebDec 12, 2016 · In addition, the geometric parameters of several crystals could be changed by using this technique. Before the Gal-8 N crystal was loaded onto the data collection unit, the crystal was exposed to room temperature for approximately 2 s. Even though this approach is different from cryoannealing, it may accomplish the same result.
