Bladder Contraction and Relaxation

The primary function of the bladder is to store urine before micturition. Alterations to the bladder contraction and relaxation of the bladder can affect filling and emptying, causing disorders such as incontinence and bladder hypertrophy. We can assess the effect of your test article on bladder smooth muscle tone using fresh functional bladder tissues.

  • Both EC/IC50 and pA2 can be determined
  • Electrical field stimulation (EFS) can be used to activate nerves that cause bladder contraction
  • Reference compounds available include carbachol, isoproterenol, and retigabine
