Unbind


Definition:

  • (v. t.) To remove a band from; to set free from shackles or fastenings; to unite; to unfasten; to loose; as, unbind your fillets; to unbind a prisoner's arms; to unbind a load.

Example Sentences:

  • (3) Physical theories have been developed to describe many aspects of their conformational behaviour, such as the preferred shapes and shape transformations of closed vesicles, and the shape fluctuations, random-surface configurations, and adhesion and unbinding of interacting membranes.
  • (4) Assuming a reversible one-to-one binding reaction, the time course of DHO binding and unbinding was analysed under a variety of conditions.
  • (5) Sanguinarine may produce a K+-like effect upon the Na pump with consequent unbinding of ouabain.

  • (7) The rate for unbinding during depolarization was independent of pHo.
  • (8) We suggest that these conformational changes arise from the unbinding to DNA of certain basic tails of histone(s), and that a competition for DNA binding locations exists upon the reassociation.
