Protein Detection with Strep-tag® Antibodies

The following monoclonal antibodies against Strep-tag® are available:

  • StrepMAB-Classic, unconjugated
  • StrepMAB-Classic HRP conjugate (HRP, horseradish peroxidase)
  • StrepMAB-Immo - the high affinity antibody for capturing Strep-tag® proteins on solid surfaces

Read our application recommendations:

StrepMAB-Classic
StrepMAB-Classic is recommended for the following applications:
  • Immunofluorescence
  • FACS
  • Detection in ELISA

StrepMAB-Classic, horseradish peroxidase (HRP) conjugate

The StrepMAB-Classic, HRP conjugate1 is recommended for detection of Strep-tag®II proteins in Western blots without the need for secondary antibodies.
1The conjugate is useful for both chemiluminescence and chromogenic detection.
StrepMAB-Immo
High-affinity Strep-tag®II specific monoclonal antibody
  • high affinity both with C- and N-terminal Strep-tag® fusion, provided the Strep-tag® is N-terminally extended by a SerAla-linker
  • for FACS analysis and Immunofluorescence staining
  • optimal for capturing Strep-tag® fusion proteins on solid phases (e.g. Biacore chips1)
  • StrepMAB-Immo coated microplates  for immobilization of Strep-tag® proteins
For Western blots use StrepMAB-Classic HRP conjugate.

StrepMAB-Classic/-Immo fluorescent conjugates

For fluorescent detection of Strep-tag® proteins in Immunocytochemistry and immunohistochemistry as well as FACS analysis

Available as single conjugates of 50 µg for different wavelengths:
  • StrepMAB-Classic or StrepMAB-Immo conjugated with Chromeo 488™
  • StrepMAB-Classic or StrepMAB-Immo conjugated with Chromeo 546
  • StrepMAB-Classic or StrepMAB-Immo conjugated with Oyster 645

Secondary HRP antibody

Rabbit anti Mouse pAb, HRP conjugated

Rabbit anti Mouse pAb, horseradish peroxidase (HRP) conjugated

Rabbit anti Mouse pAb, HRP conjugated, is recommended for detection of

  • bound mouse monoclonal antibodies, like StrepMAB-Classic, in Western blots (chromogenic reaction),
  • mouse monoclonal antibodies, like StrepMAB-Classic, in microplate assays.
