CLC Proteomics and Metabolomics Core Facility


The Proteomics and Metabolomics Core Facility at Weill Corenll Meyer Cancer Center was established in 2016. This core provides high quality proteomics and metabolomics services 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.


  • 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); other chemical labeling (dimethyl, etc.); spiked standards.
  • Post-Translational Modification Analysis: Phosphorylation; ubiquitination; acetylation; N-term / C-term processing; other PTMs.
  • Metabolomics: Detection of metabolites, drugs, and other small molecules; global profiling (untargeted or discovery); targeted quantitation.
  • RapidFire High Throughput Screening: The RapidFire unit is a micro-scale solid-phase extraction (SPE) based, front-end instrument that enables detection of native compounds by mass spectrometry. Requiring no labels or surrogates, it enables the screening of intractable or challenging targets that are not amenable to fluorescence or luminescence. Sample throughput is 10x faster than conventional LC/MS screening methods.
  • MS Data Analysis: Database searching (protein / metabolite identification); statistical analysis for quantitation; pathway analysis.
