iLab Operations Software Support will be staffed at reduced levels during the week Feb. 25 - Mar 1. iLab Support will prioritize critical issues (i.e. issues that prevent key workflows from completing). Regular support tickets will be monitored periodically. To escalate an issue, please add "Urgent" to the ticket / email subject or if dialling the iLab support phone press "1" when prompted (regional specific numbers can be found here). You can also refer to the iLab Help Site and iLab Status Page for site information.

Overview of Services

Established in 2016, the Weill Cornell Medicine (WCM) Meyer Cancer Center Proteomics and Metabolomics Core Facility provides mass spectrometry based analysis of proteins, peptides, metabolites and other biochemical molecules. The core facility is open to Weill Cornell Medicine users as well as external users from academic institutions and commercial enterprises.


  • Proteomics
    • Protein Identification
    • Protein Quantitation
      • Methods include: SILAC, TMT, Label-free, spiked standards, etc.
    • Post-Translational Modification (PTM)
      • Phosphorylation, ubiquitination, acetylation, N/C-term processing, etc.
  • Metabolomics
    • Targeted profiling of polar metabolites (Targeted detection of metabolites in a predefined panel, which includes many central metabolites such as glycolysis/TCA intermediates and amino acids. See the list HERE.)
    • Stable isotope tracing / flux for polar metabolites (e.g. C13 glucose labeling)
      • Type 1: Tracing of selected metabolites (Up to 10 metabolites from the panel can be specified. Please use compound names from the LIST to avoid ambiguity.)
      • Type 2: Full panel tracing (Exhaustive tracing of all detected metabolites. No need to know beforehand if a particular metabolite is labeled or not.) 
    • New! Thyroid hormones triiodothyronine/thyroxine (T3/T4) absolute quantitation (100 ul serum is needed)
    • New! Targeted analysis of 7 polyamines (See the list HERE.)
    • New method development

       Note:  Unless otherwise noted, quantitation in all assays is relative quantitation, not absolute.
