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!
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.
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.
For fluorescent detection of Strep-tag® proteins in Immunocytochemistry and immunohistochemistry as well as FACS analysis.
Available as single conjugates of 50µg for different wavelengths:
- Strep-Tactin® Chromeo 488
- Strep-Tactin® Chromeo 546
- Strep-Tactin® Oyster 645
