An object is to provide a pressing member, an ultrasonic probe and an ultrasonic diagnosing device that enhance the efficiency of uniformly pressing a subject and achieve a high-precision elastic image. A slot is formed in the track section, and an upwardly spring biased sensor is disposed in the slot. Moreover, the plurality of blade roller elements are associated with the at least one ski blade portion and configured to extend downward from the at least one ski blade portion. Some embodiments of the present teachings provide methods for removing unligated probes from the reaction mixture. The MSC may make this determination on the basis of information stored in a local database that indicates the method employed by other telecommunications devices, such as other MSCs, Visiting Location Registers, or Home Location Registers, within the system.
