Assay Services lab members

Assay Services provides investigators with modern, efficient, and cost-effective endocrine and biomarker measurements in a centralized facility. We provide our services to Primate Center Investigators, members of the UW Institute of Clinical and Translational Research (ICTR), other CTSA members (Clinical and Translational Science Awards), and NPRCs, as well as investigators at other universities across the United States and internationally. Our focus is to provide method development and high throughput analyses of steroids, proteins, peptides, bioamines, biomarkers, and drug compounds to aid NIH-funded research with an emphasis on non-human and human primates.
