Answer:The immobilized heparin ligand provides affinity and electrostatic interactions with suitable proteins, including antithrombin.
Answer:No. The 1 L presentation is preswollen bulk resin that must be packed into a suitable column.
Answer:It is supplied in 20% ethanol containing sodium acetate and must be equilibrated with binding buffer before loading.
Cytiva Heparin Sepharose 6 Fast Flow is an affinity chromatography resin for biomolecules that interact with immobilized heparin, including antithrombin and selected nucleic acid-binding proteins. The matrix comprises cross-linked 6% agarose beads carrying a covalently coupled porcine heparin ligand. Its average particle size is approximately 90 µm, supporting a mechanically stable chromatography bed for purification development and production workflows. The resin is supplied preswollen in 20% ethanol containing sodium acetate; remove the preservative and equilibrate thoroughly with binding buffer before sample application. Binding can involve specific affinity as well as electrostatic interactions, and increasing buffer salt concentration frequently releases retained proteins. Optimize pH, loading and salt-gradient conditions for the target biomolecule rather than assuming universal selectivity. The one-litre pack contains bulk resin for column packing, not a ready-to-use prepacked cartridge. Follow compatible storage and cleaning conditions to preserve ligand activity.
