About

Biophysics Core Facility

All Biophysics Core Users:

 

Welcome to the Princeton Biophysics Core Facility!

The Biophysics Core Facility houses a wide range of instrumentation dedicated to support biophysical characterization of proteins, DNA and several other biological macromolecules and their interactions. The newly established core facility is a joint venture of the Department of Chemistry and the Department of Molecular Biology.

Facility Use

To request training, consultation, and/or assisted services, please register with iLab.
