TopSpin

New features and applications of the latest release of TopSpin

Semi-automatic protein backbone assignment

TopSpin 2.1 introduces AUTOLINK™ that offers a semi-automatic protein backbone assignment. Due to the complexity of NMR spectral data, backbone assignment is usually a tedious and time-consuming challenge that now can be at least partly overcome by this new feature in TopSpin2.1.

Structure verification using two dimensional NMR and chemical shift prediction

TopSpin™ 2.1 introduces a new molecular structure verification tool using a powerful combination of experimental NMR data and computational tools.  The required experimental information is provided by the measured 1H-13C HSQC shift correlation data.  The computational tool is provided by an embedded plug in module in TopSpin from PERCH software that calculates chemical shifts based on the molecular structure. The two pieces of information are then analyzed, compared and reported back to the user in an easy to read visual format.
