Proteins (organs, e.g., liver, brain, muscle)
Proteins (cells)
Proteins (subcellular organelles)
Proteins (complexes)
Proteins (Western blotting)

Drugs (prodrugs, drugs and metabolites)
Xenobiotics (DES, phthalates, chlorinated compounds)
Dietary components( bioflavonoids, vitamins)
Endogenous (bile acids, steroids, lipids, peptides)

3. Which of the 1D- and 2D-electrophoresis methods below are used for your research? Indicate in the third box whether you need assistance/training in these technologies.

1D-SDS PAGE

4. Sample preparation is essential for successful 2D-proteomics and any form of mass spectrometry. Which of the following apply:

Already have a working method for proteins that has produced good results
The method(s) used in my lab always seems to identify keratins and structural proteins
Never tried preparing samples for 2D-proteomics or mass spectrometry
Interested in developing an optimal method

5. Quantitative analysis is what I need for my research. I'm interested in the following:

Peptides by iCAT and LC-tandem mass spec
Peptides by iTRAQ and LC-tandem mass spec
Peptides by multiple reaction ion monitoring mass spectrometry
Peptides by isotope dilution-mass spectrometry
Cy-dye labeling of proteins
Small molecule (drug, exogenous and endogenous) by multiple reaction ion monitoring mass spectrometry

6. Please indicate which of the following training workshops would be of most value to you. Rank each on a scale from 1-4, with 1 being the most important.

Sample preparation for 1D- and 2D-electrophoresis applications
Sample preparation for peptide mass fingerprinting and nanoLC-tandem mass spectrometry
Database searching (MASCOT and SEQUEST) for identifying proteins
Interpreting tandem mass spectra
Selecting peptide and fragment ions for quantitative analysis of peptides and proteins
Qualitative and quantitative analysis of small molecules (drugs, drug metabolites, xenobiotics, dietary factors, endogenous compounds)
