When it comes to biopharmaceutical characterization, you need a partner with established expertise and resources. As a pioneer of physicochemical characterization, we offer you unrivaled expertise in protein, carbohydrate and nucleic acid analyses. Our laboratories pioneered the development of mass spectrometric methods for the structural evaluation of a range of biotechnology product types. Many of these have now become standard procedures worldwide.
Our protein analysis package encompasses the requirements of the ICH guidelines (particularly ICH Q6B), the U.S. FDA 'Points to Consider' documents and the concept of a 'well characterized' or 'specified' biological product.
