Circular Dichroism (CD)

SGS M-Scan’s Wokingham facility is the first in the UK to offer GLP/GMP-compliant Circular Dichroism Analysis (CD), and the first to install Jasco’s latest CD Spectropolarimeter, the J-815, with class leading optical performance versatile for a range of applications, including:

  • Protein folding and conformational studies (secondary structure)

  • DNA/RNA interactions

  • Enzyme kinetics

  • Purity testing of optically active substances

  • Quantitative analysis of pharmaceuticals

  • Natural organic chemistry

  • Biochemistry and macromolecules

  • Rapid scanning (time resolved) experiments

This is a significant enhancement to SGS M-Scan’s Product Characterisation Package, tailored to the ICH Q6B guideline which require Spectroscopic Profiling as part of the assessment of the physicochemical properties of a product. All new biotechnological or biological products need spectroscopic profiling as proof of conformance to gain regulatory approval.
