Welcome to the BIDMC Mass Spectrometry Facility and John Asara Laboratory

'Specializing in a multi-omics proteomics, metabolomics & lipidomics approach'

ABOUT USThe mass spectrometry, proteomics, metabolomics and lipidomics facility at Beth Israel Deaconess Medical Center was established in 2004 led by Dr. John Asara and continues to grow rapidly. We provide excellent proteomics and metabolomics services with low prices and fast turnaround times.
We have cutting edge instruments operated at optimal sensitivity and work and publish with world class researchers. We also maintain an active internal cancer proteomics and small molecule research program. Our expertise is in identifying and quantifying protein modifications and dynamic protein-protein interactions in addition to polar metabolomics profiling, metabolic flux analysis and lipidomics profiling. We accept collaborations from anywhere in the world and look forward to helping you and progressing your research to the next level.

Post-doc/Sr Researcher position available in the lab in Multi-Omics

  • We just published a Nature Protocol article on our method for performing 13C/15N metabolic flux via polarity switching and SRM click here

  • We are awaiting funding for a new Thermo Fusion Tribid mass spectrometer

  • Our AB/SCIEX 6500 QTRAP for expanded metabolomics and 13C/15N flux work is now installed and running....

  • We upgraded our proteomics/phosphoproteomics platform with an ultra fast and ultra sensitive Thermo QExactive HF via the BIDMC Capital Equipment Award (one of Thermo's fastest and most sensitive instruments)
  • Our Lipidomics profiling platform is now operating on the Thermo QExactive Plus Orbitrap with LipidSearch and Elements software


Proteomics, Metabolomics & Lipidomics

  • Protein Complex Identification
    (protein complexes, protein-protein interactions, single protein ID)
  • Identification of Post-Translational Modifications
    (phosphorylation, acetylation, ubiquitination, etc.)
  • Relative Protein Quantification
    (MS1 based label-free quantification, SILAC, Avg. TIC, TMT, etc.)
    • Protein complex stoichiometry
    • Quantification of phosphorylation sites
    • PPI networks 
  • Quantitative Metabolomics Profiling  
    (endogenous polar metabolites from any cell or tissue source) 
    • Steady-state profiling
    • C13/N15 metabolic flux analysis
    • Untargeted metabolomics
  • Lipidomics Non-targeted Profiling 
    (High resolution; more than 66 sub-classes of lipids identified and quantified)
    • C13 lipidomic flux coming soon


  • Thermo Scientific QExactive HF Orbitrap (ultra fast and ultra sensitive for proteomics, untargeted metabolomics, etc.)
