The MMSB Biophysical Core is a shared instrument facility equipped with advanced instrumentation for characterizing biological macromolecules. The facility is in the UConn Health Center, L Wing, 3rd floor. The resources
of the facility are available to UCHC, other UCONN and external academic investigators at rates given in the fee schedule shown below. Commercial use of the instrumentation can be obtained through special arrangement.
The UCONN Health Center also has state-of-the-art NMR instrumentation for protein structure determination, stability and binding studies through the separate Gregory P. Mullen NMR Structural Biology Facility, http://structuralbiology.uchc.edu.
To gain access to the Biophysical Core Facility, contact any staff member:
Dr. Jeff Hoch, Director
phone: (860) 679-3566
Dr. Mark Maciejewski, Associate Director
phone: (860) 679-1943
Invoices will be distributed quarterly. Users from UCHC must indicate FRS coding at the time of use. Users from other UCONN campuses must arrange payment via transfer voucher.
External users may pay by check, payable to the UCONN Health Center. External users must provide a written statement from a principal investigator acknowledging and accepting the fee schedule.
