Streptavidin Agarose

Streptavidin is a tetrameric protein containing four biotin-binding sites. Recombinant streptavidin is covalently coupled to a highly crosslinked fine beaded agarose for purification of biotinylated biomolecules like proteins, lectins, antibodies, nucleic acids, receptors and ligands. The binding of biotinylated macromolecules is essentially irreversible because of the harsh conditions needed to disrupt the streptavidin-biotin interaction. This feature makes streptavidin-agarose useful in a variety of affinity purification applications.
Due to a superior coupling technology, SERVA Streptavidin Agarose provides one of the highest binding capacities available with lower non-specific binding and less leaching.
