Thank you for your interest in Refeyn’s mass photometry technology
Application note: Mass photometry of protein interaction equilibria
Learn how mass photometry can be applied to the study of complex equilibrium formation and assess how changes in the chemical environment or protein concentration affect the equilibria. More specifically, discover how mass photometry was used to study the oligomerization process of a recombinant protein that forms tetramers. Using this multimeric protein as an example, you can see how scientists measured the relative abundances of each oligomeric species across a range of physiologically relevant protein concentrations and assessed the effect of environmental factors (such as temperature) on reaction equilibria.
