•At the conclusion of a project, all extra samples will be returned to the clients only if such request was made at the time of sample submission. The Proteomics facility will not store samples long term for clients.
•At the conclusion of a project, data given to clients will include all raw data files along with processed data files and report. It will be the sole responsibility of the client to keep and store these files in a safe place.
•If on future dates the data files have to be located, processed or re-analyzed by the Proteomics facility, clients will need to supply as much information regarding the samples and files as possible. This service will be charged at a minimal fee to cover the time and effort of Proteomics core personnel. It is the sole responsibility of the clients to keep the data files and Proteomics facility is not obligated to keep these files.
Authorship credit should be given if members of the UF ICBR Proteomics & Mass Spectrometry staff have provided services or expertise that is critical to a manuscript. Although other circumstances may warrant authorship, authors are those that meet the items below:
If a member of UF ICBR Proteomics & Mass Spectrometry has contributed work to a manuscript, but does not meet the criteria for authorship, the corresponding author should acknowledge the UF ICBR Proteomics & Mass Spectrometry staff member who provided the data and their contributions should be specified.
These authorship expectations were developed in accordance with several other documents that outline criteria for authorship:
The Proteomics & Mass Spectrometry core provides a variety of services related to protein fractionation, qualitative and quantitative mass spectrometry analysis, de novo protein sequencing and protein database searching. Protein sequencing and identification are routine procedures in the lab. The capabilities in quantitative proteomics include iTRAQ (Isobaric Tags for Relative and Absolute Quantitation), TMT (Tandem Mass Tags), SILAC (Stable Isotope Labeling of Amino acids in Cell cultures), and MRM (Multiple Reaction Monitoring)-based absolute protein and metabolite quantification. Along with our capacities of separating thousands of proteins and characterizing differential protein expression, we have a suite of state-of-the-art mass spectrometers available for biomedical and advanced technology research, including a MALDI-TOF/TOF (4700 Proteomics Analyzer, AB), a quadrupole time-of-flight instrument (QSTAR Elite, AB), a quadrupole-linear ion-trap (4000 QTRAP, AB), a LTQ XL Orbitrap system, a Q-Exactive Plus Orbitrap, a TSQ Altis, and an Orbitrap Fusion (Thermo Scientific). These instruments are mainly used for accurate molecular weight determination, protein identification, post-translational modification, expression analysis (using in vitro isotope labeling (iTRAQ and TMT), SILAC in vivo labeling, and label free). Our facility is also set up to provide mass spectrometry-based N-terminal protein sequencing, sample preparation, and fractionation using HPLC. To ensure success and maximize productivity, the facility offers education, consultation, data processing and reporting, and support of grant application.
The core also provides a variety of services related to Biomarker Discovery, such as protein abundance analysis using gel-based 2 -D Fluorescence Difference Gel Electrophoresis (2-D DIGE); protein separation using 1-D or regular 2-D gel electrophoresis and Western blotting; 2-D gel-based phosphoprotein and glycoprotein profiling; Luminex biomarker discovery. For these services, we have instruments such as Ettan IPGphor, Ettan DaltSix, Typhoon Trio+ phosphor scanner, Investigator ProPic automatic spot picker, and FlexMap3D. In addition, we have image analysis software, such as GE DeCyder and Non-Linear Dynamics SameSpot Progenesis with Stats. Furthermore, the core provides protein enrichment and abundant protein depletion from biological fluids such as plasma, CSF, and urine using different techniques such as combinatory peptide (ligand) library (ProteoMiner), and assorted immunodepletion. The core also provides liquid phase preparative IEF to fractionate protein or peptide mixture using an Agilent 3100 Offgel fractionator.
