Light Scattering

The Draganova Lab is equipped to perform a variety of light scattering experiments using Wyatt Technology - use the icons below to get more information. We use an Agilent HPLC system (Infinity 1260) to operate the instrumentation.

If you are interested in using our equipment, collaborating, or learning about what light scattering can do for your project, reach out to us!

*Note: The DLS is compatible with quartz and disposable cuvettes. A quartz cuvette is needed for molar mass measurements, whereas size measurements can be done in either quartz or disposable cuvettes. The sample is recoverable from all cuvette styles. We have a quartz cuvette available for use, but we ask users to provide their own disposable cuvettes. There are two options:

Wyatt Disposable Cuvette (10 uL sample)

Generic Disposable Cuvette (500 uL sample) VWR 97000-586

As we develop our light scattering technologies, we will continue to include relevant protocols:

Size-exclusion chromatography (SEC)-MALS Protocol

The Draganova Lab thanks Dr. Kelly Arnett and the Center for Macromolecular Interactions (CMI) Core at Harvard Medical School for modification of their current protocols.
