Applications Contaminant Removal

Preserve Both Protein Yield and Quality

Astrea Bioseparations offers a range of adsorbents including affinity, anion exchange, cation exchange, and hydrophobic interaction chromatography resins to meet the challenges of process-related contaminants such as host-cell proteins (HCP), DNA, endotoxins, and unwanted glycosylated variants.

Used in flow through mode, these adsorbents selectively retain impurities while the target product passes through, preserving both the yield and quality of the target protein
