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®XT fluorescent conjugates
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.
Available as single conjugate of 50µg for:
- Strep-Tactin®XT DY-488
- Strep-Tactin®XT DY-549
- Strep-Tactin®XT DY-649
