StrepTactin

The Strep-tag® purification system is based on the highly selective binding of engineered streptavidin, called Strep-Tactin, to Strep-tag II fusion proteins. Cube Biotech offers a high-quality affinity resin for Strep-tagged proteins, with maximum binding capacity. Choose your preferred method from either agarose resins or magnetic beads.
