Sartobind® S membrane adsorbers have a macroporous structure with a pore size of > 3 µm. Sulfonic acid ligands are covalently attached to the entire inner surface of the membrane, resulting in a high-capacity separation medium combined with exceptionally high flow rates.
This membrane adsorber is successfully used in FDA-approved drug manufacturing for the removal of host cell proteins at high flow rates. As a cation-exchange, it not only shows the ability to remove aggregates but also typically has at least ten times greater binding capacity for viruses and virus-like particles (VLP).
Sartobind® S adsorber accelerates the production process with high flow rates and opens new opportunities for the purification of therapeutic proteins and vaccines.
