WCM Proteomics and Metabolomics Core Facility


2017-05 We release new services for polar metabolite profiling.

2017-01-14 Billing for Tri-Institutional Therapeutics Discovery Institute  (TDI) users through iLAB has been streamlined. Journal voucher processing will not be needed in the future.


Overview of Services

Established in 2016, the Weill Cornell Medicine (WCM) Proteomics and Metabolomics Core Facility provides mass spectrometry based analysis of proteins, peptides, metabolites and other biochemical molecules.

The resources and services of the core facility are open to all investigators at Weill Cornell Medicine, Cornell University and Cornell-affiliated institutions.  The facility also provides services to external investigators at both academic institutions and commercial enterprises.



  • Proteomics
    • Protein Identification: ID of proteins from SDS-PAGE and of proteins in-solution. 
    • Protein Quantitation: Label-free (intensity based / spectral counting); stable isotope labeling by amino acids in cell culture (SILAC); tandem mass tags (TMT); spiked standards. 
    • Post-Translational Modification Analysis: Phosphorylation; ubiquitination; acetylation; N-term / C-term processing; other PTMs. 
    • Data Analysis: Database searching; statistical analysis for quantitation.
  • Metabolomics
    • targeted profiling of polar metabolites. See the list HERE. 
    • Stable isotope tracing
    • Absolute quantitation
    • New method development

Note: High resolution instruments are used in all mass spec services.
