摘要

The most commonly available sample condition used is that of a cryo-temperature. Cooling a crystal in smaller molecule crystallography for diffraction data collection at around 100 K is the norm. In biological crystallography where X-ray radiation damage at ambient temperature is a problem this challenge is routinely ‘solved’ by cooling in an acceptable manner the crystal using a cryogen such as liquid nitrogen.
