Protein aggregation identified through UV-visible absorption spectroscopy

5 Mar 2024

Misfolded or denatured proteins can associate in solution, forming insoluble aggregates. This process is often irreversible, effectively removing useful proteins from solution and making the detection of aggregates critical for further downstream use of protein solutions. This is particularly important when studying unstable or abnormal proteins, which are more likely to form aggregates. In this application note from Thermo Fisher Scientific, explore an alternative method for the detection of protein aggregates using UV-visible (UV-Vis) absorption spectroscopy, a technique that measures a sample’s light absorption.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.
