Integrated Mass Spectrometry Unit

The Integrated Mass Spectrometry Unit (IMSU) was established at the Grand Rapids Research Center to serve the West Michigan research community and beyond. The facility was finalized with the installation of state-of-the-art mass spectrometers in February 2018 and immediately started a development phase to demonstrate our proteomics capabilities and expertise, establishing the IMSU as a formal, fee-for-service facility in September 2018.

Since the establishment of this facility, the IMSU carried out innumerable proteomics analyses, including protein identification, identification of posttranslational modification sites, global quantitative proteomics, targeted quantitative proteomics, support for drug pharmacokinetics studies, and other approaches. The IMSU has contributed to 28 grant applications of which 7 have been awarded and 3 are currently pending. The facility also contributed to 4 published research articles and 1 US patent (US Application No. 62/874544).

Dr. Irving E. Vega serves as the IMSU director, in charge of operations, project management, and scientific consultation. Day-to-day operations at the IMSU are handled by Dr. Jared Lamp, with technical support provided by Mr. Andrew Umstead. Our operations fuse sample processing with method development. We focus on timely sample analysis, ensuring that your research isn’t hindered by lengthy turnover. At the same time, we work diligently alongside our customers to optimize experimental parameters that pinpoint the most influential results. Our staff has numerous years of combined experience in high-resolution accurate-mass global and targeted proteomic method development. The facility is maintained under a rigorous quality control and assurance process.

At the IMSU, we can help guide you from early, experimental design to the final stages of data processing and everything in between. For new projects, we schedule a complimentary in-person (or Zoom) consultation that ensures you begin the project with the appropriate controls and sample preparation methods already in place.
