METHODOLOGIES WORKSHOP |
|
Tuesday, September 30, 2008 1-5 pm |
|
A new feature of the 2006 gathering, the methods workshop, will be offered again on Tuesday afternoon, September 30, for researchers interested in the state of the art. It includes introductory and advanced tutorials and hands-on proteomics science. The OPTM 2008 Methods Workshop curriculum will cover the complex of mass spectral technologies that the Core Proteomics Laboratory is fashioning into one overall proteomics approach, two-thirds lecture and one-third wet lab. The workshop will be held in conference rooms adjacent to the auditorium; attendance is limited to 45 in order to ensure the appropriate environment. The technologies that will be covered include:
|
|
Electrospray Fourier Transform (FT) Mass Spectrometry (MS) to provide the mass of intact protein samples as well as top-down sequencing and initial peptide mapping; |
|
Matrix-Assisted Laser Desorption/Ionization Time-of- Flight MS for peptide mass mapping; |
|
MALDI-FT MS for more accurate peptide mass measurement;
|
|
Laboratory detection of Thiol modifications, iodoacetamide labeling, synthesis of biotin-tagged glutathione and other labels, S-Glutathiolation, and antibodies for oxidized thiols;
|
|
Proteome Lab Protein Fraction 2-Dimension (PF2D) protein fractionation methods to analyze protein abundances and detect protein modifications;
|
|
Capillary Liquid Chromatography MS and MS/MS to automate sequencing, variant identification, and identification of post-translational modifications;
|
|
Use of MALDI and ESI hybrid FTMS instruments constructed in-house within Boston University School of Medicine’s Mass Spectrometry Resource, an NIH-NCRR Research Resource. The present BUSM instrumentation and the new cryoFTMS now under construction at the CPC will be described in the tutorial, as well as the use of commercial instruments.
|
|
Lunch will be served for workshop participants at 12:15 pm, prior to start of the session.
