About Proteomics and Mass Spectrometry Core Facility

Divison of: University of Georgia

FACILITY OPENS 15 June 2020.

The Proteomics and Mass Spectrometry Facility is equipped with an ThermoScientific Orbitrap Elite mass spectrometer for high resolution and high mass accuracy analysis. It is coupled with a nano HPLC, increasing its capacity to analyze more complex protein mixtures. The facility also has a Bruker Autoflex MALDI for quick analysis of tryptic digests of pure proteins. The facility offers in-gel digestion and subsequence analysis for protein identification. The facility also has an in-house version of Mascot that provides customers with the option of loading a database to search for protein identification. **Recent Publications** - Shen L, Macnaughtan MA, Frohlich KM, Cong Y, Goodwin OY, Chou CW, LeCour L Jr, Krup K, Luo M, Worthylake DK.

Our Services (6)


ic

ESI-MS

Electrospray Ionization Mass Spectrometry
Starting at $33.00 per sample

Samples need to be ready for analysis as facility does not include any sample clean up. Analysis is performed on a Bruker Esquire 3000 Plus ion trap. MS/MS can be requested at time of analysis of a specified ion at no extra cost. A mass spectrum can be sent via e-mail as a emf (picture) file and/or x,y coordinate file for plotting with software such as Excel. Turn around time is general less than 3 business days.


ic

High Resolution Mass Spectrometry

Starting at $49.50 per sample

High Resolution Accurate Mass ESI by sample infusion. Only manipulation of sample would be for dilution or solvation. Analysis will be performed on Thermo Scientific Velos Orbitrap mass spectrometer.


ic

Peptide Mass Fingerprinting

Starting at $55.00 per sample

Protein ID by Peptide Mass Fingerprinting (in-gel digestion, MALDI-MS, & database search). This is by TOF-MS and is good for ID of single protein in clean gel band. Performed on a Bruker Autoflex.


ic

Proteomics

Starting at $159.50 per sample

Protein ID of gel band by LC-MS/MS (60 min. run) (includes: in-gel trypsin digestion, LC-MS/MS, & one database search) Good for searching band(s) that are suspected to contain numbers proteins. Thermo Scientific Velos Orbitrap mass spectrometer coupled to a nano-LC system.


ic

MALDI Mass Spectrometry Methods

Starting at $33.00 per sample

Sample is analyzed by a Bruker Autoflex MALDI-TOF. Samples are routinely mixed with DHB matrix for analysis but facility also has alpha-cyano-4-hydroxycinnamic acid and sinapinic acid matrices available. Data is provided as an emf (picture) file and/or x,y coordinates that can be plotted using Excel.

Dennis Phillips

Director of the Proteomics and Mass Spectrometry Core
  • Positive review for ESI-MS:

    February 2020

    "Great job as always! Fast and thorough"

  • Positive review for High Resolution Mass Spectrometry:

    January 2020

    "The many samples were finished way earlier than expected, especially for it being holiday time. The data was returned in a way that exceeding expectations. Thank you for the great work guys!"

  • Positive review for High Resolution Mass Spectrometry:

    November 2019

    "The Proteomics and Mass Spectrometry Core Facility provided HRMS services quickly and generated high quality data. The scientific staff are very responsive and did a very nice job."

  • Positive review for High Resolution Mass Spectrometry:

    August 2019

    "Excellent communication. Very clear timelines and they delivered within that timeline. HRMS results were summarized in an Excel spreadsheet as well as in a PowerPoint with spectra and annotated with notes. I've worked with several other HRMS facilities and these were among the most thorough reports that I've received. I should also note that they successfully obtained data on two compounds that we could not observe ions with our in house low-res LCMS."

  • Positive review for MALDI Mass Spectrometry Methods:

    June 2019

    "Great service. I would like to work with 'Proteomics and Mass Spectrometry Core Facility' again."

  • Positive review for ESI-MS:

    March 2019

    "We always use this laboratory, and are always pleased with the fast and great service!"

  • Positive review for MALDI TOF MS:

    January 2019

    "Great service! Fully professional, knowledgeable and helpful!"

  • Positive review for ESI-MS:

    March 2018

    "Always a great service, good data, fast turnaround. Have used successfully for many years."

  • Positive review for MALDI TOF MS:

    July 2017

    "Not only the product was excellent, but the willingness to engage in a dialog to make sure that the experiment was the correct one was outstanding. I will certainly work with them again in the future!"

  • Positive review for Peptide Mass Fingerprinting:

    June 2017

    "Results were in sooner than expected."

  • Positive review for High Resolution Mass Spectrometry:

    June 2017

    "The Proteomics and Mass Spectrometry Core Facility provided high quality service with fast turnaround. Couldn't be happier."

  • Positive review for ESI-MS:

    May 2017

    "Dennis Phillips was very responsive to all of my requests for information. The spectra were provided in a timely fashion with complete details on the analysis as requested. This was a great experience. I highly recommend this mass spectroscopy group."
