Protein Analysis FS Core
Step 1 Information Required
  • The following information will be required to
    insure the researcher obtains appropriate FS
    Core services
  • Sample type? purified protein, simple mixture
    (less than 10 proteins), or complex mixture
    (e.g., cell lysates, biological fluid like serum)
  • Amount of sample?
  • Information desired?relative protein abundances
    or comparative analysis with no identification of
    proteins, relative protein abundances or
    comparative analysis with subsequent
    identification of proteins, protein
    identification only, or protein identification
    plus additional characterization of protein
    modification(s)

Step 2 Initial Consultation
  • Once initial information is obtained
  • Contact Protein Analysis FS Core Leader to
    schedule consultation
  • During consultation, appropriate facilities and
    services will be determined
  • Investigator will be instructed on sample
    submission and appropriateness and mechanisms of
    CEG supplement

CEG

Protein Analysis FS Core
Step 3 Data Review
  • After services have been obtained
  • Facility staff will work with investigator on
    obtaining results
  • When necessary, consultation with bioinformatics
    specialists will be arranged to review data and
    findings

Protein Analysis FS Core
Proteomics Pilot Projects/Additional Workshops
  • The Protein Analysis FS Core is arranging to
    issue a request for new mini-pilot projects in
    proteomics.
  • First such project funded development of protein
    profiling (Michael Borchers)
  • Emphasis on projects requiring integration of
    sample preparation/data collection/data analysis
  • Expectation will be one project requiring
    existing capabilities and another project
    developing new skill sets within the core
  • The Protein Analysis FS Core will also be
    hosting several additional hands-on training and
    research-oriented workshops. Training/Workshop
    topics or ideas are welcome.
