The Chirascan system at the Manchester Institute of Biotechnology is used to advance biological, biochemical, and medical research.  Our scientists use CD to gain an understanding of how mutations, buffer or stress conditions affect protein structure and to confirm the stereostructure of small molecules.  The system is routinely used by more than 25 scientists and is typically in use 90% of the time.  The system is intuitive making user training straightforward.  Users return to the Chirascan because it is highly reproducible, has excellent signal:noise and delivers results quickly.

I’ve been using Applied Photophysics Stopped-Flow products for the past three decades. I made my first purchase as an independent researcher in 1999. The Stopped-Flow instruments have served me well, their longevity and robustness is a standout feature. When I moved from Florida Institute of Technology to Texas A&M University in 2014, I did not hesitate to upgrade from the SX18 to the latest generation SX20. The range of accessories and upgrades available for the instrument is very impressive – I still continue to add accessories and features to my instrument. The instruments are easy to use, they have very intuitive software and the technical support provided is of the highest quality but with a personable approach.

The Chirascan-plus CD spectrometer is an important instrument of our biophysical core facility. The facility is a part of the Centre of Molecular Structure (CMS),  of the Czech Infrastructure for Integrative Structural Biology (CIISB) and belongs to the Czech centre of the Instruct-ERIC European infrastructure for structural biology. The goal of CMS is to provide shared resources of instruments and technologies for a variety of users from both the academic and industrial communities and to offer the expertise on a wide range of topics in biophysics and structural biology. We use Chirascan-plus for the determination of the secondary structure of proteins, understanding of the impact of point mutations on protein structure and stability, as well as for studies of conformational diversity of oligonucleotides in temperature ramping experiments. Chirascan-plus is very reliable and can produce excellent results for both experienced and novice users.

Applied Photophysics provided us with prompt, high quality support during the relocation of the Chirascan system into our Biophysical Analysis core facility.  The instrument offers excellent performance and the thorough training supplied has served as a solid foundation for our now established expertise in circular dichroism.  At present, the user base (and publication list) is steadily growing as more and more researchers realise the value of a quick check for correct folding of their site directed mutant proteins.  Other applications include analysis of nucleic acids and determining stereo chemistry of small chiral molecules.

The Chirascan CD spectrometer in the Imperial College London Molecular Science Research Hub is one of the most popular pieces of equipment on campus. We are a group of physicists, chemists and materials scientists who study the optical and electronic properties of conjugated chiral materials. The simple, rapid and reliable characterisation – in both the solution and solid state – afforded by the Chirascan is central to our optimisation of these materials for their application in devices. To date, our research has focussed on circularly polarised (CP) Organic Light Emitting Diodes and CP Organic Photodetectors, but thanks to the Chirascan, we can create and analyse materials with strong chiroptical effects for a range of novel applications. The ease of operation, high signal-to-noise and highly responsive customer support team make the Chirascan accessible to every member of our research team. Alongside the standard spectrometer, the low cost user-inspired accessories (for example, to measure circularly polarised photoluminescence or optical rotatory dispersion), which can be added on to the set-up at any time, set the Chirascan apart from other equipment on the market.

CD spectroscopy is an important tool for my research group enabling us to deepen our understanding of the rules which govern self-assembly of chiral molecules.  We have used the Chirascan instrument to measure Absorbance, CD, LD, ORD, FDCD, Fluorescence (Emission & Excitation Scanning) data of organic compounds in the 200 to 800 nm wavelength region. We found that the instrument easy to use, reliable and to deliver excellent results regardless of the type of measurement.  When time allows, the Chirascan is a favourite for researchers from other groups wishing to make isothermal and thermal denaturation measurements of protein and DNA – probing structure and stability.  It is clear that the biochemists like the Chirascan because they have recently bought their own!

I am very happy with the service of Applied Photophysics. I am always amazed at how fast James responds. Most companies charge an arm and a leg for software updates. Another company has even forced me to buy a pre-installed computer saying they don't support user-supplied PC anymore. So for each update, I have to buy a PC from them now! Not with Applied Photophysics.
