Affinity Chromatography Resins

Affinity chromatography remains one of the most powerful and selective techniques for protein and biomolecule purification, exploiting highly specific biological or chemical interactions. It is widely used for therapeutic protein capture, antibody purification, vaccine processing, and impurity removal, offering unmatched selectivity and efficiency.

Built on decades of expertise in agarose bead technology, Astrea Bioseparations’ affinity resins represent the foundation of our company and continue to be a cornerstone of our existence. Our unique portfolio includes products such as AlbuPure® for albumin-fusion capture, EtoxiClear® for endotoxin removal, MAbsorbent® for human IgG purification, and Mimetic Blue® for albumin-related protein capture, alongside specialist adsorbents for proteases, glycoproteins, and other biomolecules.

These solutions highlight our commitment to innovation and partnership with the biopharmaceutical industry. Designed to deliver high binding capacity, robust performance, and consistent scalability, Astrea’s affinity resins enable reliable purification strategies that support the development of life-changing therapies.
