> **NIH NIH S10** · UNIVERSITY OF WISCONSIN-MADISON · 2020 · $313,267

## Abstract

PROJECT SUMMARY
In this proposal, the Assay Services Unit, a core lab at the Wisconsin National Primate Research Center
(WNPRC) requests a Sciex 6500+ LC-MS/MS with ExionLC AD to enhance capabilities and improve throughput.
The Assay Services Unit provides NIH-funded investigators validated quantitation of biomarkers in biological
samples for a variety of species. The ultra-sensitivity afforded by increased ion transfer, the expanded mass
range and fast polarity switching of this mass spectrometer will serve 3 major aims: 1) Provide the ability to
create quantitative peptide/protein panels utilizing capabilities that only exist with state-of-the-art LC-MS/MS, 2)
Expedite development of methods in the method development queue that are critical to NIH-funded research for
Major and Minor Users and 3) Provide Users with reduced turn-around time for data and serve as a secondary
instrument for uninterrupted progress through the sample queue. As presented in this proposal, there are 8 Major
NIH-funded and 4 Minor Users that demonstrate a strong need for the methods that will be developed on the
requested instrument to facilitate their research. Acquisition of the Sciex 6500+ will advance health goals in a
number of diverse fields which include improving outcomes after neonatal brain injury, understanding
psychosocial determinants of healthy aging and determination of the biological effects of displacement due to
political conflict in mothers and children. The Major and Minor User group for the new Sciex 6500+ includes 12
investigators from the WNPRC, the University of Wisconsin-Madison (UW-Madison) and from academic
institutions outside of UW-Madison. These Users include established investigators with developed research
programs and many years of funding as well as early career investigators. The requested instrument will join the
suite of assay methodologies that are offered in the Unit and permit Assay Services to create new, cutting-edge
methods. The Unit has a record of almost 40 years of documented success in utilizing new technology to develop
validated assays that provide data of high rigor and reproducibility.
