Common Use Departmental Equipment

Mass Spectrometry:

The departmental mass spectroscopy facility has a new Bruker Microflex MALDI-ToF equipped with PSD capabilities for peptide sequencing and a software suite consisting of Flex Control, Flex Analysis, BioTools, and Polytools. The software suite is capable of performing a MASCOT search to identify proteins from MALDI-ToF data. Polytools allows for the analysis of synthetic polymers using MALDI-TOF data.

There is also a new Thermo Finnigan LXQ ion trap instrument equipped with an Accela HPLC and autosampler. The LXQ is capable of MSN data acquisition using the Xcalibur software suite. The software suite on the LXQ comes complete with BioWorks and Mass Frontier, which allow for protein identification and the deconvolution of complex spectra.

 

Other Spectroscopy Equipment:

Adjacent to the mass spectroscopy core is a new Thermo Fisher UV-Vis spectrophotometer, Thermo Nicolet FT-IR, and a new PTI FRET Master II spectrofluorometer. (Additional UV/Visible spectrophotometers, a polarimeter, and multiple HPLC setups can be found in the research labs.)

Nearby is a workhorse Varian 300 MHz multi-nuclear NMR and the department has shared ownership of the 500 MHz NMR housed in the Polymer Science Research Center.

Newly installed instrumentation includes a Bruker 400 MHz NMR and a Bruker X-band EPR as well as a Jasco J-815 Spectropolarimeter (CD and ABS measurement modes).
