Abstract

Summary: We introduce here a novel acquisition and processing methodology for cross-polarization based 1D rotating-frame relaxation dispersion NMR experiments. This easy-to-use protocol greatly facilitates the screening, acquisition, processing and model fitting of large on- and off-resonance R1ρ relaxation dispersion NMR datasets in an automated manner for the analysis of chemical exchange phenomena in biomolecules.

Availability and Implementation: The Amaterasu package including the spreadsheet, Bruker pulse programs and analysis software is available at www.moleng.kyoto-u.ac.jp/∼moleng_01/amaterasu.
