StrepTactin® Superflow™ Agarose is a cross-linked agarose derivatized with StrepTactin protein. The binding capacity is 50 to 100 nmol/ml settled resin, or up to 3 mg of 30 kDa protein per ml settled resin. It can be used for gravity flow as well as for low pressure and FPLC chromatography. StrepTactin Superflow Agarose is optimized for column affinity chromatography as opposed to batch purification. It is supplied as a 50% slurry.
