Mass Spectrometry


The mission of the Mass Spectrometry (MS) Core in the LSU Health-Shreveport Research Core Facility is to provide efficient and cost effective proteomics and metabolomics based services for research investigators.

The facility is located in room F6-12, in the Biomedical Research Institute. For protein analysis, our principal approach is bottom-up proteomics, which is a common method to identify protein and characterize their amino acid sequences and post-translational modifications by proteolytic digest prior to analysis by mass spectrometry. In addition to our developed standard operating procedures offered for many of our MS services, we also strive to continue to bring, state-of-the-art mass spectrometry based analyses through input and request from our users.


The Mass Spectrometry Core was established to provide service to the complete biomedical community at LSU Health-Shreveport.  Although samples will be run by facility staff, we expect users to familiarize themselves with sample preparation, data acquisition and interpretation and be an active part of sample analysis.


For all publications that include data generated in the Mass Spectrometry Core, we kindly request that you acknowledge this support:
