MS & Proteomics Resource

Resource Description

The Mass Spectrometry (MS) & Proteomics Resource of the W.M. Keck Foundation Biotechnology Resource Laboratory provides efficient and cost effective proteomics and small molecule mass spectrometry based services. Beside from our developed Standard Operating Procedure (SOP) offered for many of our MS services, we also strive to continue to bring state-of-the-art mass spectrometry based biotechnologies through input and request from our users. 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. 

Our services include: 

  • Basic Protein ID from gel bands 
  • Protein ID from complex solution 
  • Protein Posttranslational Modification (PTM) identification 
  • Protein profiling and quantitation (Labeled Free Quantitation, iTRAQ, TMT, & SILAC) 
  • Intact Protein Determination. 
  • High Resolution (HR) MS for small molecule. 
  • Targeted Proteomics (PRM) 
  • Metabolomics Biomarker Assay (utilizing Biocrates p180)

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. Though we will do our very best to ensure (by looking through literature and other sources) that the highest quality services are provide for every sample that are 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.

Samples storage

Please note that due to the large number of samples that go through our facility, we have implemented the following policy for post sample preparation storage.  We advise that if you want to keep these samples, please let us know as soon as you receive your results.

-Submitted gel samples will be discard 1 year post sample prep date.

-Submitted cells/tissues/solution/plasma/etc. (non-gel) samples will be discarded 2 years post sample prep date.
