Proteome-Wide Monitoring of Drug Action in Living Cells Using a Novel Label-Free Solvent-Based Shift Assay

Biophysical proteomics assays allow for proteome-wide, label-free monitoring of ligand-induced changes in protein structure and stability, offering insights into protein-ligand interactions and modulation of biophysical properties of cellular proteins. These assays exploit the principle that compound-induced alterations in structure or stability of proteins can be detected through changes in their susceptibility to denaturation. Here, we introduce solvent proteome profiling in cells (SPICE), which employs solvent-based denaturation of proteins under otherwise physiological conditions in...
