      DescriptionAnti-Strep-Tag Antibody, clone C23.21
      Alternate Names
      • Strep-Tag II
      Background InformationStrep-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.
