The Children's National Research Institute

Proteomics Core


The proteomics core laboratory at Children’s National Research Institute (CNRI) is located in the Center for Cancer and Immunology Research. It provides an excellent technological platform to support and advance the basic and clinical research at CNRI and the George Washington University (GWU). The laboratory is equipped with state of the art mass spectrometry instruments including Thermo Q Exactive HF mass spectrometer coupled online to Easy-nLC 1000 nano-flow UPLC system, and Q Exactive mass spectrometer coupled to Dionex Ultimate 3000 RSLCnano system. 

Services offered by the proteomics core include:

  • Basic protein identification from gel bands and/or protein mixtures digested in solution
  • High throughput protein identification in cell, tissue, body fluid samples
  • Quantitative proteomics using stable isotopes (e.g. SILAC, TMT) as well as label-free approach
  • Targeted proteomics applications
  • Consultancy in project design and support for proteomics related grant components 
  • Training in sample preparation, proteomic data analyses and integration

We provide complementary consultancy, training and education in new technologies. At this time each user is responsible for his / her sample preparation. Our charges for LC-MS/MS analysis is highly cost effective, and based on mass spectrometer usage time at $45 / hour. We strive to provide a superior turnaround time for most sample analyses.
