Can a tagged protein be detected in situ?
Yes. It can be detected via EM or FM with streptavidin which is labelled with colloidal gold or FITC. • Has the Strep-tag® technology been tested in Biacore analysis? Yes. StrepMAB-Immo, high-affinity Strep-tag® II specific monoclonal antibody [Cat.-No.: 2-1517-001], is optimal for capturing SerAla-Strep-tag® II fusion proteins on solid phases such as Biacore chips or microplates.
