Strep-Tactin Superflow combines superior mechanical stability and outstanding flow characteristics with high dynamic binding capacity.

It is suitable for increased flow rates and is also useful for the purification of large protein complexes. The Strep-tag® / Strep-Tactin® purification system allows the isolation of above 95% pure and functional proteins after one chromatographical step. The Strep-tag system is based on the highly selective and easily controllable interaction between the Strep-tag II peptide and the specially engineered streptavidin called Strep-Tactin.

The binding affinity of Strep-tag II to Strep-Tactin is nearly 100 times higher than to Streptavidin.
Binding capacity: 50 to 100 nmol recombinant Strep-tag protein (up to 3 mg in case of a 30 KDa protein) per 1 ml bed volume.

Gravity flow Strep-Tactin Superflow column, 1 x 1 ml; also available 5 x 0.2 ml , 5 x 1 ml, 1 x 5 ml and 1 x 10 ml columns.
