Jasco high-performance circular dichroism (CD) spectrophotometers

Click2Contact

Circular dichroism (CD) measurements can be used to determine the secondary structure content of a biomolecule to elucidate the relationship between structure and function or verify protein stability.

The J-1500 CD spectrometer allows measurements with high signal-to-noise (S/N) ratio in the vacuum-UV region down to 163 nm. It incorporates several of the latest technologies, such as digital lock-in detection (up to four data channels), high-throughput optics (minimises risk for sample degradation), double prism design (provides low stray light) and an effective nitrogen gas purging system. These features ensure that CD spectra can be obtained from both strongly absorbing and high S/N samples across the spectrum and into the vacuum-UV region and as a result should enable more accurate protein secondary structure analysis.

The J-1500 CD spectrometer has been designed as a multipurpose, flexible system with a wide dynamic range to meet demanding CD applications with high sensitivity. The high-throughput (HTCD) system offers automated protein secondary structure estimation.

The Jasco CD series also includes the J-1100 CD spectrometer, designed for routine, conventional CD applications in a compact package; and the J-1700 CD spectrometer, designed for more demanding near-infrared CD applications such as magnetic CD and covering the wavelength range from UV, visible and NIR up to 2500 nm.
