Biophysical Instrumentation Core Facility

The CSB maintains a variety of instruments for studying the conformation and stability of macromolecules and for measuring the affinity and thermodynamics of biomolecular interactions. To set up core access and training, contact Alex Fisch. If you have additional questions or would like to set up a consultation, contact Heather Kroh.
