Description The Jasco J-1500 is the Highest performance CD spectrometer that allows studying absorption spectra and circular and linear dichroism spectra in the spectral region of 163 – 950 nm(Far-UV to VIS). When combined with a wide range of sampling accessories, the J-1500 allows for the maximum flexibility to upgrade your CD study with different measurement techniques. These accessories can measure a variety of samples, from liquids to films to solid-states. 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. Uses: Determination of protein secondary structure Determination of optical purity Analysis of the tertiary structure of proteins and conformational changes Comparison of the secondary and tertiary structures of wild-type and mutant proteins Binding studies involving conformational changes Nucleic acid structure and changes upon binding or melting Thermodynamic parameters from temperature dependencies of CD signals Kinetics of conformational changes on msec timescales Quantitative analysis of pharmaceuticals
