title: Saturation transfer difference NMR for fragment screening.
abstract: Fragment screening by saturation transfer difference nuclear magnetic resonance (STD-NMR) is a robust method for identifying small molecule binders and is well suited to a broad set of biological targets. STD-NMR is exquisitely sensitive for detecting weakly binding compounds (a common characteristic of fragments), which is a crucial step in finding promising compounds for a fragment-based drug discovery campaign. This protocol describes the development of a library suitable for STD-NMR fragment screening, as well as preparation of protein samples, optimization of experimental conditions, and procedures for data collection and analysis.
