Circular Dichroism
Circular dichroism (CD) spectroscopy is a form of light absorption spectroscopy that
measures the difference in absorbance of right- and left-circularly polarized light
(rather than the commonly used absorbance of isotropic light) by a substance.
The J-1500 Circular Dichroism spectrophotometer in our facility is specifically designed
for high sensitivity measurements in the near- and far-UV regions, for scientists
that need confidence in the data from characterization studies of biomolecule structure,
function and stability under a wide variety of experimental conditions. Temperature
control systems can be coupled with multi-position cells to run thermal melts, providing
researchers with CD and thermodynamic data sets for conformational and folding studies.
