Pioneering Biophysical Characterisation Since 1970

Applied Photophysics of Leatherhead, Surrey, UK, is a leading provider of solutions for the biophysical characterisation of biomolecules. With over five decades of innovation, we have been at the forefront of spectroscopy for life science research.

Our Chirascan™ systems use circular dichroism (CD) to characterise changes in the higher-order structure of proteins—critical for innovator drugs and biosimilars. The SX range of stopped-flow spectrometers is the global gold standard for kinetic studies of fast biochemical reactions.

Through a joint venture with Fluorescence Innovations Inc., operating as Protein Stable, we offer high-throughput protein stability screening with microplate-based intrinsic fluorescence thermal ramping and chemical melt plate readers.

Frequently Asked Questions

What is circular dichroism (CD) spectroscopy?

CD spectroscopy measures differences in the absorption of left and right circularly polarized light. It is used to study the secondary and tertiary structure of proteins and nucleic acids.

How does stopped-flow work?

Stopped-flow rapidly mixes small volumes of reactants and stops the flow abruptly, allowing the observation of fast reactions on millisecond timescales using various detection methods.

What are the advantages of nano-DSF?

nano-DSF requires no dyes or labels, uses minimal sample volume (2–10 µL), and enables high-throughput screening of protein stability under various conditions.

Do you offer international support?

Yes, Applied Photophysics has service engineers and distributors in over 40 countries, including direct offices in the UK, US, and China.
