WebNov 1, 2024 · 3.2. Time-dependent unit cells, mosaicity and Wilson B factors in cold crystals. When crystals are cooled to ∼140 K or below, vitrified internal solvent immobilizes the protein atoms and the crystal diffraction properties are (in the absence of radiation damage) independent of time. As crystals are warmed from ∼140 to ∼190 K, solvent ... WebJan 1, 2003 · Disorder can be described as long range or short range. In general long-range disorder in the crystal gives rise to localized effects in reciprocal space and vice versa. 1, 2 For example, crystal mosaicity, which is a large-scale property in real space, causes the localized effect of broadened spots in reciprocal space. Random disorder between ...
