CETSA® MS

Tracking drug action in living cells
  • CETSA® MS enables proteome-wide target identification without the need for a label on the compound or the protein
  • Thermal stability can be used to monitor protein-ligand interactions for up to 7,000 proteins in living cells or lysates
  • The technology provides an unbiased measure of drug-target engagement and facilitates identification of markers for drug efficacy and toxicity
