Keck Mass Spectrometry & Proteomics Resource
Building: 300 George Street, G001
About the core
The Keck Mass Spectrometry (MS) & Proteomics Resource at the Yale School of Medicine provides efficient and cost-effective proteomics and small molecule mass spectrometry-based services. Aside from our developed standard operating procedures (SOPs) offered for many of our MS workflows, we also strive to continue to bring state-of-the-art mass spectrometry-based biotechnologies and methodologies to the Resource through input and requests from our users and collaborators. These technologies are developed and implemented with a broad spectrum of mass spectrometry-based techniques and protein/peptide/small molecule chemistries to separate, characterize, profile, and quantify analytes from complex biological samples.

Disclaimer
Due to their high complexity and variability, we cannot guarantee that our SOP for sample preparation will be applicable to all proteomics samples that we receive. ALL CLAIMS, REGARDLESS OF THEIR NATURE, MUST BE BROUGHT TO OUR ATTENTION WITHIN 30 DAYS OF RESULTS DISSEMINATION. However, we will do our very best to ensure (by looking through literature and other sources) that the highest quality services are provided for every sample submitted to us.
THE MS & PROTEOMICS RESOURCE SHALL NOT BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL, OR UNANTICIPATED OUTCOME RESULTING FROM SAMPLE PREPARATION INCOMPATIBILITY TO OUR SOP, NOR SHALL ITS LIABILITY IN ANY CASE EXCEED THE ESTIMATED COST OF THE SERVICES RENDERED.

Our history
The Mass Spectrometry & Proteomics Resource of the W.M. Keck Biotechnology Resource Laboratory at Yale’s School of Medicine had its beginnings in 1980 in the Department of Molecular Biochemistry and Biophysics.
Dr. Kenneth R. Williams founded the Keck Lab, then called the Protein Chemistry Facility. He is still director of the resulting and evolving Keck Lab, which now encompasses Proteomics, Genomics, Biostatistics, and Bioinformatics.
