JASCO J-1000 series CD spectrophotometers

CD spectroscopy is generally considered an essential tool for the secondary structure analysis of proteins, particularly in the UV region below 260 nm. While synchrotron radiation is an effective method to measure the CD spectra of protein film samples in the vacuum-UV region, it requires access to a limited number of facilities.

As an alternative to synchrotron radiation, 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 (providing 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, enable good protein secondary structure analysis.

Based on over 50 years of experience, the Jasco J-1000 series includes the J-1100 CD spectrometer, designed for routine, conventional CD applications in a compact package; the J-1500 CD spectrometer, designed as a multipurpose, flexible system with a wide dynamic range to meet demanding CD applications with high sensitivity; 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.
