Strep-Tactin®

Strep-Tactin® is a streptavidin variant, which can be utilized for coating of different surfaces. It is optimized for the binding of Strep-tag®II and Twin-Strep-tag® 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).
