Thermal Shift Assays are innovative techniques employed in protein characterization to unravel the intricacies of thermal stability and unfolding. These assays play a pivotal role in understanding how proteins respond to temperature changes, providing critical information for various applications, including drug discovery and protein engineering.

How does Thermal Shift Assays work?

  1. Fluorescent Dye Binding: Proteins are mixed with a fluorescent dye that binds to hydrophobic regions exposed during protein unfolding.
  2. Temperature Ramp: The protein-dye mixture is subjected to a controlled temperature ramp. As the temperature increases, the protein undergoes thermal unfolding.
  3. Fluorescence Detection: The fluorescence of the dye changes as it interacts with the exposed hydrophobic regions of the unfolding protein. This change in fluorescence serves as a reporter for protein unfolding.
  4. Inferring Stability: By monitoring the temperature at which unfolding occurs, researchers can infer the thermal stability of the protein. Proteins with higher thermal stability will resist unfolding at higher temperatures.
