Image-iT® FX signal enhancer is a liquid that is applied directly to slides or coverslips containing fixed and permeabilized cell or tissue samples prior to staining with fluorescent probes. When Image-iT® FX signal enhancer is used, nonspecific fluorescence (background) commonly seen with the application of fluorescent conjugates of streptavidin, goat anti-mouse, or goat anti-rabbit IgG is largely eliminated.

Key Attributes

Easy protocol—apply enhancer from ready-made solution in dropper bottle
Effective with many fluorescent labels (see Table 2 in user manual below)
Cost effective—supplies enough for 50 standard coverslips
Compatible with your immunostaining protocol’s other blocking steps

Reduce Nonspecific Binding of Dyes to Tissues.
Alexa Fluor® dyes and many other dyes have negatively charged modifications that can lead to nonspecific association with cells and tissue. While not always significant, it can be a problem when pushing the limits of sensitivity in low-abundance targets. Image-iT® FX signal enhancer can significantly reduce this binding, resulting in marked improvements in staining.
