Abstract
The WaterLOGSY (WL) and saturation transfer difference (STD) NMR experiments have proven to be extremely useful techniques to characterize interactions between small molecules and large biomolecules. In this work we compare the relative sensitivities of WL and STD NMR using 3 experimental systems: ketoprofen (KET)-bovine serum albumin (BSA), tert-butyl hydroquinone (TBHQ)-hemagglutinin (HA), and chloramphenicol (CAM)-ribosome (70S). In all cases we find that WL is more sensitive than STD for a given experimental time with the ratios ranging from 3.2 for KET-BSA to 16 for TBHQ-HA and CAM-70S. We attribute the increased sensitivity of WL to be due to simultaneous saturation of multiple sources of cross correlation, including direct NOEs of 1H of water and exchangeable groups and indirect NOEs of 1H-C groups. We suggest that the outstanding sensitivity of WL make it ideally suited for drug screening efforts targeting very large biomolecules at relatively low concentrations.

Abstract
The binding affinity and specificity of heparin to proteins is widely recognized to be sulfation-pattern dependent. However, for the majority of heparin-binding proteins (HBPs), it still remains...

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...

[Question from NMRWiki Q&A forum] Saturation transfer difference TROSY
Saturation transfer difference TROSY
Has anyone added a pulse scheme for cross saturation to their TROSY for Bruker platform?
Could you share a pulse sequence if you have one?
Thanks!
