Mass Photometry Webinars

We have hosted a range of webinars, where we discuss applications of mass photometry as well as how to get the best out of our technology. You can watch any of them on this page. To stay updated on upcoming webinars, please check out our events calendar.

Measuring Membrane Proteins with Mass-Sensitive Particle Tracking

In this webinar, Dr Nikolas Hundt (Ludwigs-Maximilian-University Munich), describes a new mass photometry strategy for unlabelled molecules diffusing on supported lipid bilayers. With this approach, called mass-sensitive particle tracking (MSPT), researchers can determine the mass distributions and diffusion characteristics of membrane-associated protein complexes and observe protein assembly dynamics on a lipid interface in real time.

Quantifying protein-protein interactions by molecular counting with mass photometry

Dr Grzegorz Piszczek (Director of the Biophysics Core Facility, NIH) and Fabian Soltermann (PhD candidate, Oxford University) discuss how mass photometry can be used to characterise and determine the purity, stoichiometry, binding affinity and kinetics of multi-protein interactions. They also cover a recent application of mass photometry: quantifying interactions of antibodies with Fc-receptors.

Measuring Molecules with Light

This webinar features our co-founder, Prof. Philipp Kukura, describing how mass photometry offers a universal way to study biomolecules, as well as its strengths and limitations.

Using Mass Photometry to Quantitate CaMKII stoichiometries

Prof. Margaret Stratton (UMass Amherst) presents her work on the role of CaMKII​ in different tissues. Mass photometry helps to quantitatively determine the stoichiometry of different variants of this crucial oligomeric enzyme.

Measuring the heterogeneity of macromolecular machines by mass photometry

In this webinar, Dr Adar Sonn-Segev presents how mass photometry provides quantitative information on sample heterogeneity using minimal volumes with molecular resolution. She also discusses how this approach applies to several different workflows including chemical crosslinking and multi-step purification, comparing it to the standard tools for measuring sample purity.

Applications of Mass Photometry

In this webinar, Refeyn co-founder Prof. Justin Benesch discusses examples of mass photometry measurements for large protein complexes and draws comparisons with mass measurements obtained from native mass spectrometry and other techniques. Dr Nikolas Hundt also describes the use of mass photometry to visualise the nucleation process of actin filaments in real time.
