Image-iT FX Signal Enhancer ReadyProbes Reagent dramatically reduces background fluorescence resulting from non-specific staining during secondary detection using conjugates of streptavidin or secondary antibodies. This reagent is applied directly to slides or coverslips containing fixed and permeabilized cell or tissue samples prior to staining with fluorescent probes.


  • Easy protocol—apply ready-made solution using a dropper bottle
  • Compatible with the other steps in your immunostaining protocol
  • Effective with most fluorescent labels
  • Stable at room temperature—keep handy at your scope or cell culture area
