Mass Spectrometry and Tandem MS/MS
Instrumentation and Services Available
An ABSciexTripleTOF 5600+, an ABSciex 5800 Proteomics Analyzer (MALDI TOF-TOF), a Waters Synapt HDMS with Ion Mobility capacities, an MDS-Sciex 4000 QTrap, and a Voyager DE-PRO (Perseptive Biosystems) are available for analyses of protein, peptide, lipid, small molecule, and oligonucleotide samples. Analysis of digests of highly complex mixtures, such as whole cell lysates or serum proteins, commonly yield identification of 600-6000 proteins from single samples, & identification of proteins purified by column chromatography, by metal affinity chromatography, by gel electrophoresis, or from PVDF/nitrocellulose membranes are also available, e.g., detection of phosphoproteins and other post-translational modifications, isozyme analysis, & identification of disulfide bonds.
Additional analysis such as metabolite ID, Lipid ID, or targeted protein ID/quantitation using peptide SRM/MRMs are also available.
Discovery quantitation of differences in protein amount between samples can be done by in vivo SILAC metabolic labeling or iTRAQ isotope tagging post-harvest (up to 8 separate samples with 500-2500 proteins ID'd and quantitated in single experiments), or by MS identification of spots of interest on 1D/2D gels. For quantitation of lists of pre-determined proteins of interest, peptide SRM (MRM) assays can be developed to allow rapid sequential relative or (with heavy isotope peptide standards) absolute quantitation of proteins of interest. Finally, combined ID and label-free quantitation ("Qual/Quant") analyses can be performed using Data-Independent Analysis (DIA) SWATH methods

In addition to using classic gel spot densitometric (2D Gels) or fluorescence (DIGE Gel) measurements to find proteins whose levels differ between two or more samples, identification and quantitation of protein level changes can be done by using chemical isotope labeling methods. In such methods, one tags all proteins from different samples with identical chemical tags that differ only in their distribution of heavy and light (non-radioactive) isotopes of the same atoms, e.g., 1H vs. 2H, 12C vs 13C, 14N vs. 15N. Where possible, this can be done in living cells or animal models by feeding heavy vs. light isotope versions of various naturally incorporated amino acids (sometimes called SILAC methods); however, for many studies such pre-labeling is not possible. In such cases various chemical isotope incorporation methods are available. We previously performed many analyses with Isotope Coded Affinity Tag (ICAT) methods, and over the past 7 years (2006-2013) we have used Isobaric Tags for Relative and Absolute Quantitation (iTRAQ) methods to perform many hundreds of large scale analyses of complex samples, including human serum samples, animal and plant cell lysates, and cell organelle preps. Such experiments typically identify and quantitate the relative amounts of 500-2500 proteins from 4-8 samples at once (see further details below).
Standard sample separations for iTRAQ experiments done in the Mass Spec Facility (after the iTRAQ reagent labeling step) are identical to those for an LC-MALDI MudPit experiment:
- Separation of the combined 4 or 8 iTRAQ-labeled samples offline into 15 strong cation exchange fractions, using a 4.6 X 250 mm PolySULFOETHYL Aspartamide Strong Cation exchange column (PolyLC, Columbia, MD) with an ammonium formate gradient in 20% acetonitrile. (Details of these protocols can be viewed at "2D LC Procedures Used")
- SpeedVac drying and resuspension in H2O of all fractions (3X) to remove all acetonitrile and ammonium formate.
- Separation of each SCX fraction on a 15 cm Reprosil C18 nanoflow column on an Eksigent ChipLC system, and direct injection into our ABSciex 5600 TripleTOF mass spectrometer (For MALDI analyses, separation of each SCX fraction on an LC-Tempo nanoflow separation and MALDI spotting system, using a Chromolith CapRod column C18 column (150 X 0.1 mm, Merck), into 370 MALDI spots on a stainless steel MALDI target plate, then adding 13 calibration spots to the same target plate).
- Instrument is calibrated with an injection of beta-gal digest standard before each sample injection (For MALDI analyses, update plate calibration and MS/MS default calibration for each plate as it goes into our Applied Biosystems 5800 MALDI TOF TOF mass spectrometer).
- A 250 ms parent scan is acquired, then up to 50 MS/MS spectra over 2.5 seconds, then repeated with the next LC eluant fraction. (For MALDI analyses, acquisition of 400 laser shots for MS spectra from each spot, then data-dependent acquisition of MS/MS spectra for each peptide mass, with the MS/MS spectra taken from the spot containing the largest MS peak representing each of the peptide peaks observed across the entire plate).
- Combination of the MS/MS data from all 15 SCX fractions for a Paragon algorithm search (ProteinPilot 4.5 Software as of Jan 2013, against a concatenated normal and reversed database (SwissProt, NCBI, etc.). This search of a concatenated normal and reversed database allows estimation of the False Discovery Rate (or False Positive Rate) so that one can set the score limits for "positive IDs" to only accept IDs where the local False Discovery Rate estimate of the lowest ranking protein is 5%, and all higher ranking proteins have decreasingly lower probabilities of being false positives (See "Calculating False Discovery Rates" for more information on the importance of using False Discovery Rate estimations and how they are calculated.
The resulting ProteinPilot .group files can be viewed with a Windows XP or later computer by installing a trial version of the ProteinPilot Software once the trial period is over, you can continue to use the software as a viewer for .group files produced by our licensed versions of the software.
Many Small Molecule analyses (polymer analysis, validation of synthesized compounds) can be performed as a walk-up service on our Voyager DE-PRO Reflectron MALDI instrument in room C1734 (after training by Core personnel on the use of the instrument).
More complex analyses requiring MS/MS and MS3 fragmentation, or requiring electrospray-, APCI-, or photo-ionization are performed on one of three mass spec instruments.
Our ABSciex TripleTOF 5600 with a Shimadzu UFLC-XR separation system (C1735), and our Waters Synapt HDMS with Ion Mobility and a Waters Acquity UPLC separation system (C1733), provide strong capacities for small molecule, lipidomic, and metabolomic analyses. Please contact Dr. Dongxiao Sun (email@example.com) to arrange analyses using these instruments.
The MDS/Sciex 4000 QTrap (C1733) includes a PAL CTC temperature-controlled auto sampler, an Agilent 1100 2D LC system, all standard quadrupole and ion trap MS modes, and various enhanced modes for increased sensitivity and selectivity. This instrument includes the possibility of MS^3 analyses, as well as additional ionization modes possibly advantageous for analyses of some types of molecules (APCI or PhotoIonization).

Using the Proteus & Geneus LIMS System for Sample Submission and Data Retrieval
- Getting a Proteus/Geneus LIMS account - see instructions below.
- Click HERE to log on to the Proteus LabLink System for Data Retrieval or Sample Submission
- Click HERE to log on to the Geneus LabLink System for Data Retrieval or Sample Submission
Instructions for obtaining a LIMS account:
Signing Up for a Proteus/Geneus LIMS LabLink Account (download PDF of instructions below)
Note that Proteus LabLink & Geneus LabLink are very similar, but SEPARATE LIMS systems - an account on one system does NOT allow you access to the other system, you must have TWO accounts, one for each system:
- Proteus serves the Mass Spec, Flow Cytometry, and Microscopy Imaging Cores
- Geneus serves the Functional Genomics and DNA Sequencing Cores
For your username fill in your Penn State Access Account ID (e.g., bas12). (For external customers, before you can request a LabLink account you will need a Friends of Penn State ID, which you can apply for by following the "Create an Account" link and instructions at https://fps.psu.edu/ )
For your username fill in your Penn State Access Account ID (e.g., bas12). (For external customers, before you can request a LabLink account you will need a Friends of Penn State ID, which you can apply for by following the "Create an Account" link and instructions at https://fps.psu.edu/ )
3). When your account request has been approved by IT (usually takes 2-3 days), you will receive an email with your username and temporary password, which you can then use to login to Submit Sample/Analysis Requests or Retrieve Data as follows:
a). For Proteus LabLink, log in at: https://proteuslablink.med.psu.edu/lablink/Login.do
b). For Geneus LabLink, log in at: https://geneuslablink.med.psu.edu/lablink/Login.do
4). The first time you log on to either system, please change your password to something you can remember.
