Strep-Tactin(R)

Strep-Tactin(R) is a streptavidin variant, which can be utilized for coating of different surfaces. It is optimized for the binding of Strep-tag(R)II and Twin-Strep-tag(R) fusion proteins but still maintains the ability to capture biotinylated targets. Therefore, it can be used for assay development and protein interaction studies, including experiments such as proximity-dependent biotin identification (BioID).
