WCM Proteomics and Metabolomics Core Facility


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

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

2016-10 Proteomics core is open. 


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 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.
