Cellular Thermal Shift Assay (CETSA®)

Our biophysicists can incorporate the use of the CETSA® platform into your integrated project via our alliance with Pelago Bioscience. The CETSA® platform provides a label free physiologically relevant measure of affinity allowing the demonstration of direct target engagement. Pelago Bioscience, founded by the inventor of CETSA® platform, is the industry leader in the application of the CETSA® to study target engagement.

CETSA® involves heating cell lysates to different temperatures and quantifying the presence of target protein in the soluble fraction by western blotting or mass spectrometry. It is suitable for studying target engagement in lysates, intact cells and tissue and is applicable to a wide range of soluble intracellular and extracellular drug targets, capable of resolving potencies from mM to fM.
