- Note: due to the pandemic, for sample drop-off, please schedule a time in advance with core staff to ensure that someone will be in the lab.
- June 2022 Upgraded proteomic profiling assay using Data Independent Acquisiton (DIA) enables deep coverage and accurate quantitation without the need of isotope labeling.
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
- Proteomic profiling by label-free quantitation
- Label-free quantitation enables straightforward experimental design.
- With improved data independend acquisition (DIA) methods, typical number of protein IDs ranges 5,000-7,000 for human/mouse total cell lysate.
- Popular applications: protein expression profiling; protein interactions (IP); proximity-based labeling for interactome mapping (APEX) etc.
- Proteomic and phosphoproteome profiling by TMT quantitation (See a Sample report. )
- Stable isotope labeling enables high accuracy in quantitation. Ideal for deep coverage phosphoproteome analysis.
- Allows comparing up to 18 samples in a single experiment.
- Typical number of protein IDs 6,000-8,000, phosphosites 10,000 - 20,000 for human/mouse total cell lysate.
- Popular applications: global phosphoproteomics; Thermo Proteome Profiling (TPP)/Cellular Thermal Shift Assay (CETSA), etc.
- Post-Translational Modification (PTM) analysis
- Popular applications: PTM characterization of purified protein; histone modifications profiling(See details HERE); crosslinking proteomics, etc.
- Types of PTM include: Phosphorylation, ubiquitination, acetylation, N/C-term processing, etc.
- Identification of gel purified proteins
Popular applications: confirmation of protein expression, 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).
