Abstract

During air drying by ultrasonic pulseecho method, the longitudinal sound velocity of tetragonal hen-egg-white (HEW) lysozyme crystals were measured. It was found that the sound velocity increased with exposure to open air and approached a constant value. Further, the sound velocity recovered to original one after immersing the dried crystal in solution. Therefore, the sound velocity in tetragonal HEW lysozyme crystals can be reversibly changed due to rehydration and dehydration.
