SlowFade® Gold antifade reagents suppress photobleaching and preserve the signals of your fluorescently labeled target molecules for analysis. SlowFade® Gold antifade reagent does not cure over time so samples can be viewed immediately. SlowFade® reagents are intended for short-term preservation (3–4 weeks), and samples may degrade over longer periods.

SlowFade® Gold antifade reagent is best for immediate analysis and short-term storage. For long-term analysis and choose one of our ProLong® Gold antifade reagents.
SlowFade® Gold performance
SlowFade® Gold antifade reagent outperforms all other commercially available antifade reagents because it preserves signal across the entire visible spectrum and causes little or no quenching of the initial fluorescent signal.
