Strep-tag® Purification System is based on the highly selective binding of engineered streptavidin, called Strep-Tactin®, to Strep-tag® II fusion proteins
Four Strep-Tactin® resin versions are available which differ in their properties and the available column formats:
For batch purification use our MagStrep Strep-Tactin® coated Magnetic Beads.
- Strep-Tactin® Sepharose is preferentially used for gravity flow chromatography
- Strep-Tactin® Superflow®
- Strep-Tactin® Superflow® high capacity
- Strep-Tactin® MacroPrep® (can also be used for low pressure or FPLC applications)
