See ‘Wyatt Technology‘ for a feature on the D’Arcy Group. We use size-exclusion chromatography coupled to light scattering to characterize our protein complexes as various stages of our purification and analytical pipeline. We have a Wyatt miniDAWN TREOS and Optilab T-reX downstream of an AKTA pure. Graduate student Prithwijit Sarkar should be commended for his work in setting up this approach in the lab.
