 Thermo Scientific Pierce Biotin Agarose provides for unusual affinity purification experiments involving clean-up or removal of streptavidin or avidin protein components.
Pierce Biotin Agarose is beaded agarose support onto which biotin moieties have been covalently immobilized. Typical avidin-biotin affinity procedures use immobilized avidin or streptavidin proteins to capture biotin-tagged molecules from a sample. Occasionally, however, the reverse situation arises in which immobilized biotin in needed to capture avidin or streptavidin components from a sample. This biotin resin addresses this special situation. Biotin Agarose (also called immobilized biotin) binds avidin and streptavidin very strongly, making it appropriate for non-reversible binding applications.
Highlights:
- Enable purification or removal of avidin or streptavidin samples
- Crosslinked beaded agarose onto which biotin is covalently immobilized
- Use Biotin Agarose for non-reversible binding (e.g., removal of avidin components from a sample)
