FIELD: chemistry of proteins.
SUBSTANCE: invention describes a method for drying protein crystals from an aqueous suspension of protein crystals. Suspension of protein crystals are dried in centrifugal drier by drying gas wherein drying gas before the drying process is wetted with water and protein crystals after their filtering off from suspension of protein crystals are placed in drying medium consisting of a mixture of water and non-aqueous solvent mixed with water in any ratio that show vapor pressure value lower than water. Drying gas wetted with water is used preferably. For drying the suspension of protein crystals is transferred into fluidized layer preferably. Method provides preparing protein crystals with the definite water content.
EFFECT: improved drying method.
