Laboratory Equipment

1. NMR Equipment:500 MHz magnet during charging500 MHz magnet during charging

We use equipment, which is part of the shared Brown Univeristy Structural Biology Core Facility.

The Peti Lab has access to the Brown University Biomolecular NMR Facility, located the Laboratories of Molecular Medicine, 70 Ship Street, which houses one Bruker NMR instrument operating at 500 MHz. The main use of this NMR instrument is high-resolution NMR spectroscopy of biomacromolecules. The NMR spectrometer is accordingly equipped:

  • AVANCEII 500 MHz spectrometer (DRU receiver) is equipped with four independent channels dedicated to 1H, 13C, 15N, and 2H (2H-TX board). Two automated tuning and matching probes are available for the 500 MHz instrument: a room temperature TXI HCN z-gradient probe and a TCI HCN z-gradient cryoprobe. The instrument is controlled via TopSpin 3.1 on a Linux based computer.
  • The AVANCEIIIHD 850 MHz spectrometer (TCI HCN z-gradient cryoprobe).The instrument is controlled via TopSpin 3.2 on a Linux based computer.


2. X-Ray Equipment:

The Peti Lab has access to the Brown University Biomolecular X-ray Facility, located the Laboratories of Molecular Medicine, 70 Ship Street. Crystallographic equipment includes a Rigaku/MSC FRE+ generator (copper anode), CCD detector and X-stream liquid nitrogen source for crystal screening and data collection at cryogenic temperatures at a single wavelength. Art Robbins Instruments Phoenix Art Robbins Instruments CrysCam Multiple Puck systems for automatic screening at the synchrotron (we mainly use X25/29 at NLS).
