Ensuring Target Protein Purity

Chromatographic purification of therapeutic proteins from complex biological sources is an essential step to ensure the quality and safety of the final product.

Astrea Bioseparations’ range of affinity chromatography adsorbents are designed for high specificity and high binding capacities for target proteins in large scale biomanufacturing applications, while delivering optimal purity. Our proprietary agarose beading process delivers PuraBead® matrices that are easier to pack, with improved flow characteristics.
