Extherid Biosciences is a woman-owned specialty contract research organization that works collaboratively with partners to deliver a range of biological research and technology development services. Our mission is to provide innovative, accelerated, and high-value services to optimize preclinical research and help ensure successful clinical trials.

We have a unique approach to contract research, which begins with founder Dr. Marnie Peterson’s twenty plus years of experience creating and developing new drugs and medical devices. A strong relationship with our partners is at the core of our philosophy. We tailor our models to help you meet your research goals.

Customizable ex vivo models are our go-to preclinical research technique. Unlike in vitro models, ex vivo testing can meaningfully predict clinical conditions without the added time and expense of potentially unnecessary in vivo testing.

The results from our studies will give you the insight you need to develop and perfect your antimicrobial formulations, cosmetic and skincare products, implantable devices, and wound dressings.
