Our Workflow


Quality, ethical, and sustainability standards

We are dedicated to the procurement of ethically sourced tissues.

  • Farm to lab bench: we work with local farmers and can obtain tissue from organically raised animals.
  • Porcine tissue comes from pigs raised in accordance with USDA guidelines and slaughtered for human consumption.
  • We keep sustainable practices in mind and are committed to minimizing our impact on the environment by reducing waste and reusing/recycling laboratory supplies whenever possible.
  • We follow ASTM International standards when applicable.

Why Jackson?


Jackson, Wyoming's natural beauty, low population density, and no income tax are a welcome alternative to the high-traffic urban biotech clusters in California, Massachusetts, and Texas. Established in 2016, Extherid Bioscience has quickly attracted advisors, talent, and investors who are passionate not only about their work but also about the Jackson way of life. From local farmers to the school system and the regional hospital, the community of Jackson has welcomed and supported Extherid's growth. We are happy to call this area our home.
