ready-to-use, 10x conc.
Protein free blocking reagent for immunocytological assays.



Suitable for


  • Immunocytological assays
  • Immunohistological assays
  • Paraffin- and cryosections
  • in situ hybridisation
  • Cell culture samples
  • Whole mount samples


ImmunoBlock is an innovative blocking reagent on a polymer base without detergents and proteins.


This particular composition provides the following advantages:

  • No contamination of your detection system through foreign proteins,
    reducing background and false-positive signals
  • Specific binding signals are preserved whilst non-specific interaction is impeded, increasing the signal-to-noise ratio
  • Ready-to-use solution for fast and easy applications
