Sartobind® Pico 0.08 ml Capsule Size Completes Portfolio of Salt-Tolerant Membrane Adsorbers

Sartobind STIC ® PA membrane binds contaminants under high-salt buffer conditions

(PresseBox) (Göttingen, Germany / Aubagne, France, )
Polishing in antibody production is usually performed on quaternary ammonium (Q) membranes in flow-through mode, since the overall speed and productivity is much higher than on traditional anion-exchange columns. However, the binding capacity of Q ligands is reduced at higher conductivities, so concentrated feed streams must be diluted to adequately remove contaminants such as DNA, host cell proteins, viruses and endotoxins.

Sartobind STIC PA (primary amine) anion-exchange membrane overcomes this limitation and binds contaminants at high conductivities under high-salt conditions at up to 20 mS/cm. The salt-tolerant anion exchanger can directly process cation-exchange pools without further dilution. Buffer consumption and jwnxlz ecex gshfeuthaaj ely xf sqbissp.
