  Protein crystals are generally wet and fragile, thus easily suffer from dehydration and temperature change. To preserve the crystals from such sudden physicochemical conditional changes, we developed a crystal mounting method, humid air and glue coating (HAG) method. This method works well to maintain most protein crystals under both cryogenic and room temperature conditions. Room-temperature measurement has recently advanced in time-resolved analysis by serial femtosecond crystallography (SFX) method using X-ray free electron laser (XFEL) facilities, and emerges dynamical properties of proteins, leading to its recurrence even in synchrotron experiments. Here we show the brief guidance to the method and its application, and discuss the perspective of room-temperature structural analysis in macromolecular crystallography.
