Q PuraBead HF


SKU: 3452 Category:


Q PuraBead® HF is a high-performance strong anion exchange chromatography adsorbent designed for capture, intermediate or polishing steps for the purification of negatively charged biomolecules.

Q PuraBead® HF ligand is a quarternary ammonium (Q) group coupled to highly cross-linked monodisperse 6% agarose (PuraBead® HF) which has excellent flow properties. The adsorbent is stable in up to 1.0M sodium hydroxide which allows for stringent cleaning and sanitization protocols.
