In observance of the upcoming holidays, Agilent Cross Lab iLab Operations Software will be closed during US hours on Monday December 25th, 2017 and Monday January 1st, 2018. EU and APAC will be closed on Tuesday December 26th, 2017. During the week, we will have limited support hours and resume regular support hours on Tuesday January 2nd, 2018. For urgent matters, please add "URGENT" to the ticket subject and these requests will be prioritized first.



To submit a help ticket with iLab, click on the HELP link to access the support portal. If you are unable to access the support portal, email and this will create a ticket. iLab Support can also provide you with access to the support portal.

Please Acknowledge

In order to continue obtaining Core support in a challenging environment, it is crucial that our users acknowledge the following grants in all publications (see following text).  Thank you!


This work was supported in part by Cancer Prevention Research Institute of Texas (CPRIT) grant number RP130397 and NIH grant number 1S10OD012304-01.


Overview of Services

Mission.  The mission of the Proteomics and Metabolomics Core Facility is to provide the research community with cutting-edge expertise and services for sensitive, precise, and accurate measurement of proteins and metabolites using mass spectrometry-based technologies.





  • Protein Identification: High sensitivity (silver stain OK), up to 100 proteins or more may be indentifiable. 
  • Molecular Weight Determination: Check the MW of your peptide or molecule.  Proteins may be measured if enough clean protein is available (larger proteins are less reliable). 
  • Quantitative Protein Analysis:  Using stable isotope methods, iTRAQ, etc. For SRM/MRM methods on our tandem quadrupole MS, please inquire. Quantitative Protein Profiling using MRM, HRM or DIA (Swath-like) methods, with or without reference peptides (lists available, custom lists can be built).
  • Posttranslational Modification Analysis:  Phosphorylation, acetylation, methylation, etc. Please inquire for more detailed information.
  • LC-MS Analysis:  Size exclusion chromatography and simple LC-MS.  Please inquire for more detailed information and other chromatographic analyses available.



  • Targeted
  • Amino Acids (30): Quantitative LC-MS assay for measurement of the 18 proteogenic amino acids and 12 related molecules. (See List Below)
  • Organic Acids (8): Quantitative LC-MS assay for measurement of 8 organic acids. (See List Below)
  • Glutathione (2): Quantitative LC-MS assay for measurement of reduced (GSH) and oxidized (GSSG) glutathione. (See List Below)
  • Polyamines (14): Quantitative LC-MS assay for measurement of 14 polyamines (See List Below)
  • DNA Damage Metabolites (6): Quantitative LC-MS assay for measurement of 6 DNA damage metabolites (See List Below)


  • Non-Targeted
  • Profiling: Quantitative LC-MS assay for measurement of metabolites in non-targeted fashion; multiple configurations available.
  • Tracer Analysis: Quantitative (ratiometric) LC-MS assay for measurement of stable isotope label incorporation into non-targeted metabolites.


Additional Data Analysis:

  • Additional Data Analysis: Bioinformatics, statistics, pathway analysis, and/or assistance preparing materials for manuscripts or presentations. (For data from within the Proteomics/Metabolomics Core (Internal) and other types of data from outside this Core (External), i.e. Genomics, RPPA, Microarray, Sequencing, etc...)
  • Drug Combination Analysis: 3-dimensional surface response analysis of drug combinations incorporating multiple additivity models for the statistical determination of synergy, additivity, or antagonism (Please contact Phil Lorenzi to discuss prior to submitting data for this analysis)
