Thermo Scientific™ Pierce Immunostain Enhancer enables significant antibody dilution (5- to 20-fold beyond normal) to increase signal intensity 3- to 12-fold in immunostaining applications with chromogenic or fluorescent substrates.

This ready-to-use enhancer for immunohistochemical staining does not add steps to the workflow because it is used to dilute the primary and secondary antibodies. The Pierce Immunostain Enhancer is compatible with fluorescence and chromogenic detection and routinely increases both signal intensity and detection sensitivity. Signal enhancement is antibody-dependent and typically ranges from 3- to 12-fold. Because of the strong signal enhancement, the Pierce Immunostain Enhancer reduces the amount of antibody required to achieve optimal detection.


  • Save precious antibody – Pierce Immunostain Enhancer allows the customer to use only a fraction of antibody to achieve the same signal as with conventional immunodetection

  • Convenience – simply replace your current antibody dilution buffer with Pierce Immunostain Enhancer (unlike other signal enhancement methods which require additional steps)

  • Increased signal intensity and sensitivity – provides 3- to 12- fold increase in signal intensity and sensitivity for improved visualization of the antigen of interest in cells and tissues

  • Improved specificity – significantly improves signal-to-noise ratio for poor quality and low affinity antibodies

  • Compatible – can be used with chromogenic and fluorescent detection methods
