Beschreibung

General description

Strep-Tag is a short amino acid-peptide sequence that exhibits specific binding to streptavidin. It is shown to reversibly occupy the same pocket where biotin is normally complexed. Hence, it is highly desirable for applications involving where efficient purification of fusion proteins. Use of this tag allows for easier detection of fusion proteins in various immunochemical assays. Strep-Tag is shown to be resistant to the action of proteases and can also be used in the presence of mild detergents. Clone C23.21 recognizes fusion proteins with Strep-Tag peptide sequence WSHPQFEK with picomolar affinity. It recognizes both the single and the double Strep-Tag sequence.

Immunogen

Recombinant ectodomain of glycoprotein E2 of GB virus (GBV-B), containing a double Strep-Tag (two Strep-Tags separated by a linker peptide)

Application

Quality Control Testing

Evaluated by Western Blotting with Strep-Tagged VHH 9.

Western Blotting Analysis (WB): A 1:500 dilution of this antibody detected Strep-Tagged VHH9.

Tested Applications

Surface plasmon resonance: A representative lot detected Strep-Tag in Surface plasmon resonance application. (Meola, A., et al. (2015). J Virol. 89(4):2170-81).

Western Blotting Analysis: A representative lot detected Strep-Tag in human brain extract and GFAP in Western Blotting applications. (Li, T., et al. (2017). Immunol Lett. 188:89-95).

Immunohistochemistry Applications: A representative lot detected Strep-Tag in mouse brain tissue sections in Immunohistochemistry applications (Li, T., et al. (2017). Immunol Lett. 188:89-95).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
