The HyperCel™ STAR AX is a high-capacity anion exchange chromatography sorbent designed for high-salt solutions. Users can capture target protein directly from feedstock at conductivities of up to 15 mS/cm—no unit operations of ultrafiltration/difiltration or dilution required. A high dynamic binding capacity at short residence times (100 mg/mL BSA at 1–2 min residence time) can further streamline downstream processing.
