About Us

Applied Photophysics of Leatherhead, Surrey, UK, is a leading provider of solutions for the biophysical characterisation of biomolecules and has been providing spectroscopy to the research community for over 50 years. Chirascan™ systems use the phenomenon of circular dichroism (CD) to characterise changes in the higher-order structure of proteins. These systems are used in cutting-edge research and to support the development of innovator drugs and biosimilars in the biopharmaceutical industry.

The company’s SX range of stopped-flow spectrometers is acknowledged globally as the gold standard for kinetic studies of fast biochemical reactions. Through a joint venture with Fluorescence Innovations Inc of Minneapolis, MN, USA, operating as Protein Stable, we have also introduced easy-to-use high-throughput protein stability screening with microplate-based intrinsic fluorescence thermal ramping and chemical melt plate readers.
