Detection of Metabolite-Protein Interactions in Complex Biological Samples by High-Resolution Relaxometry: Towards Interactomics by NMR

19 January 2021, Version 1

Abstract

In this manuscript, we introduce an NMR method to investigate the interaction of metabolites and other small molecules with proteins in biological fluids. Our approach, based on high-resolution relaxometry identifies the interaction of small molecules with proteins in blood serum and is used for the quantitative analysis of binding competition in situ.
