Title:
タンパク質結晶の乾燥方法
Document Type and Number:
Japanese Patent JP4465120
Kind Code:
B2
Abstract:
The present invention relates to a process for drying protein crystals starting from an aqueous protein crystal suspension, which comprises drying the protein crystal suspension in a centrifugal dryer, where the protein crystals, after they have been filtered off from the protein crystal suspension, are brought into contact with a drying medium which consists of a mixture of water and a nonaqueous solvent which is miscible with water in any ratio and which has a lower vapor pressure than water. In the process, a drying gas which has been moistened with water is advantageously used. The protein crystal suspension is advantageously converted into a fluidized bed for the purpose of drying.
