Penta·His Biotin Conjugate

For sensitive detection of His-tagged proteins

  • Highly specific and sensitive detection of His-tagged proteins
  • Flexible detection using any steptavidin or avidin conjugate

In detection procedures, the Penta·His Conjugate binds to a protein's His tag and the complex is localized using avidin derivatives, such as streptavidin, which can be conjugated to fluorescent dyes (e.g., streptavidin-R-PE) or to other proteins (e.g., HRP, AP) used in detection procedures.
