Cryocrystallography has become an essential and routine tool in structural biology over the last decade as a result of observation of great reduction in radiation damage to protein crystals during X-ray diffraction experiments at cryotemperatures (Low et al., 1966; Haas and Rossmann, 1970). As radiation damage was becoming a limiting factor in the utilization of synchrotron radiation sources in the early 1990s, a simple loop-mounting method was developed for cryocrystallography by former BioCARS staff scientist Tsu-Yi Teng (Teng, 1990). The method is now widely and routinely used by the majority of protein crystallographers at synchrotron and laboratory X-ray sources.
