Protein Detection with Strep-Tactin® Conjugates

Strep-Tactin® conjugates are available as:

  • Strep-Tactin® HRP conjugate (HRP, horseradish peroxidase)
  • Strep-Tactin® AP conjugate (AP, alkaline phosphatase)
  • Strep-Tactin® fluorescent conjugates for different wavelength

The HRP-conjugate is used for direct detection of Strep-tag® fusion proteins in Western blots via chromogenic and/or chemiluminescence reaction. The AP-conjugate is used for direct detection of Strep-tag® fusion proteins in Western blots via the chromogenic reaction. No secondary antibody needed!

Strep-Tactin® HRP conjugate

For chemiluminescence or chromogenic detection of Strep-tag® proteins on Western blots, we offer:

  • Strep-Tactin® horseradish peroxidase (HRP) conjugate (2-1502-001) for direct detection without the need for a secondary antibody. For details please refer to the Western blot protocol.
Strep-Tactin® AP conjugate

For chromogenic detection of Strep-tag® proteins on Western blots or ELISA we offer:

  • Strep-Tactin® alkaline phosphatase (AP) conjugate for direct detection without the need for a secondary antibody.
Fluorescent Strep-Tactin® conjugates

For fluorescent detection of Strep-tag® proteins in Immunocytochemistry and immunohistochemistry.

Available as single conjugates of 50µg for different wavelengths:

  • Strep-Tactin® Chromeo 488
  • Strep-Tactin® Chromeo 546
  • Strep-Tactin® Oyster 645
