Services

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

  • Proteomics
    • Protein Identification
      • protein in gel / in solution
    • Protein Quantitation
      • Popular applications: protein expression profiling; protein interactions (IP); proximity-based labeling for interactome mapping (APEX); Thermo Proteome Profiling (TPP)/Cellular Thermal Shift Assay (CETSA); Targeted Protein Degradation (TPP), etc. 
      • Methods include: SILAC, TMT (See details HERE), Label-free, spiked standards, etc.
    • Post-Translational Modification (PTM)
      • Popular applications: protein phosphorylation profiling; PTM characterization of purified protein; histone modifications profiling(See details HERE); crosslinking proteomics, etc.
      • PTMs include: 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. See a Sample report. )
    • Stable isotope tracing / flux for polar metabolites (e.g. C13 glucose labeling. See a Sample report. )
      • Type 1: Tracing of selected metabolites (Please select metabolites 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. Note: minimum 6 samples) 
    • Untargeted metabolite profiling (See details HERE.)
    • Lipid profiling (See the list HERE.)
    • Free fatty acid profiling  (See the list HERE.)
    • Bile acids  (See the list HERE.)
    • Acylcarnitine profiling  (See the list HERE.)
    • Short chain Acyl-CoAs  (See the list HERE.)
    • Folate metabolites  (See the list HERE.)
    • Thyroid hormones triiodothyronine/thyroxine (T3/T4) absolute quantitation (100 ul serum is needed)
    • Targeted analysis of 7 polyamines (See the list HERE.)
    • Accurate MW measurement (HRMS) for drugs/chemicals (mass accuracy: a few ppm)
    • New method development

       Notes: 

    • Unless otherwise noted, quantitation in all assays is relative quantitation, not absolute.
    • Turnaround time is normally 5-10 business days, except for global protein/PTM profiling (~4 weeks).
