About Us

Company Overview

In 1987, a Cambridge University working group spun out under the name Affinity Chromatography Limited. Through the years, the name and owner changed, including time as Prometic Bioseparations before being sold in late 2019 and subsequently rebranding to Astrea Bioseparations.

We are a Gamma Biosciences company, focused on helping to bring small and large molecule, and advanced therapies to market with industry leading bioseparation adsorbents and resins.

Our team is honored to supply reliable, world class resins for more than 21 FDA and EMA approved manufacturing processes.

What’s in a Name?

Astrea was the Greek “star-maiden” goddess of justice, innocence, purity, and precision. Taking the name Astrea Bioseparations reflects our own focus on purity, precision, and humanity in all we do. Astrea was represented by the constellation Virgo, which we frequently apply for the striking resemblance to a molecular diagram.
