PureCube HiCap StrepTactin MagBeads

The term Strep®-tag refers to an eight amino acid long (WSHPQFEK) protein affinity tag that can be used for affinity chromatography based protein purification. It is based in the increadible specificity of the protein StrepTactin ® that interacts with the specific amino acid squence WSHPQFEK. By taking advantage of this incredible specificity maximum protein puritiy levels through affinity chromatography can be obtained
Our PureCube StrepTactin Agarose resin beads consits of 6% cross-linked agarose that are coupled to the StrepTactin protein. PureCube StrepTactin ® MagBeads yield up to 7 mg protein per ml used MagBead solution. Furthermore we also offer PureCube StrepTactin ® XL MagBeads for more viscous cell lysates.
As an alternative to magnetic beads Cube Biotech also offers PureCube StrepTactin® agarose resin for FPLC and batch spin based protein purification.
