The present invention discloses a method to discover selective inhibitors of phosphatases. Thus the invention provides a method for screening a test compound to determine whether the compound binds a holophosphatase selectively or non-selectively comprising: i) providing a first holophosphatase wherein said holophosphatase is captured/immobilised; ii) testing a test compound for its ability to bind to the first holophosphatase; iii) providing a second holophosphatase wherein said second holophosphatase is captured/immobilised; iv) testing the same test compound for its ability to bind to the second holophosphatase; v) comparing the binding of the test compound to said first holophosphatase with the binding to said second phosphatase wherein a compound that binds a holophosphatase selectively will bind to said first holophosphatase but not said second holophosphatase; or will bind to said second holophosphatase but not said first; or wherein a compound that binds a holophosphatase non-selectively will bind to both said first holophosphatase and said second holophosphatase.
