An Introduction to PBL

Our Story

The Precision Biomarker Laboratories (PBL), a commercial proteomics contract research organization, was founded in 2019 with a vision to reliably accelerate the steep and costly path of translating biomarker discovery into clinical applications and commercialization. With an established portfolio of innovative technologies derived from Dr. Jennifer Van Eyk’s research accomplishments, Dr. Susan Mockus joined PBL to transform the vision into reality, recognizing the transformative potential and value that decades of proteomics expertise could provide with thoughtful translation.  


Today, Precision Biomarker Laboratories stands as an exceptional team of biomedical experts operating in a dynamic and high-touch research environment, committed to enhancing clinical value for our clients.  Situated in Beverly Hills and supported by Cedars-Sinai Medical Center, one of the largest research hospitals in the U.S., our state-of-the-art proteomics facilities are helmed by a diverse group of scientists with expertise ranging from discovery proteomics to targeted panel development.


Our talented and innovative team is the reason PBL is the preferred proteomics service provider for the Global Health Discovery Collaboratory platform at the Bill and Melinda Gates Foundation and cater to a wide spectrum of research needs in the pharmaceutical and biotechnology industries, as well as academic and government organizations.
