  • Publication number: 20040219584
    Abstract: Methods are provided for altering the cleavage specificity of a Type IIG restriction endonuclease, the Type IIG restriction endonuclease being characterized by a cleavage domain adjacent to a methylase domain, the methylase domain located adjacent to a specificity domain. The method includes ligating DNA or protein sequences to form a fusion DNA or fusion protein. Where a fusion DNA is formed, the host cell is transformed with the fusion DNA to express a Type IIG restriction endonuclease with altered cleavage specificity.

  • Publication number: 20030199116
    Abstract: An IC-integrated, flexible, shear-stress sensor skin is made by providing a wafer with integrated circuits and sensor elements which are fabricated in the wafer, disposing a first polymer layer on the wafer and sensor elements to provide mechanical support for the sensor elements, defining a cavity below the sensor elements to provide thermal isolation, while the sensor element remains supported by the first polymer layer, and isolating the sensor elements into a plurality of islands defined in the wafer, so that the islands, with at least one sensor element on at least one of the islands, and the integrated circuits form the IC-integrated, flexible, shear-stress sensor skin. The invention is an IC-integrated, flexible, sensor skin made according to the method.
