ProLong™ RapidSet™ Antifade Mountant

ProLong RapidSet Antifade Mountant is an advanced, hard-setting mounting medium designed to expedite the imaging process for fluorescently labeled biological samples. This aqueous two-component system hardens in less than one hour, enabling rapid preparation times without compromising imaging quality or sample protection.

Key features and benefits

• Easy application—simply apply a drop of each component directly onto the sample. The sequence of addition does not affect the curing process, helping make it user-friendly and straightforward.
• Rapid curing—the two-component system hardens within one hour, dramatically reducing the time needed before imaging and enhancing workflow efficiency
• Exceptional fluorophore protection—it protects fluorescent dyes and proteins from photobleaching across the entire visible and near-infrared spectra, helping ensure bright and stable fluorescence signals
• Optimal refractive index—achieves a high refractive index of approximately 1.5 after one hour, closely matching that of glass coverslips and immersion oil, which minimizes optical distortion and maximizes image resolution
• Versatile use—suitable for widefield, Z-stack, and spectral imaging, it can be used wherever a hard-setting mounting medium is required
• Sample archival—designed for long-term storage of slides, it maintains sample integrity for weeks or even months, making it excellent for archival purposes with strong and stable fluorescent signals
• Convenient storage—store components at 4°C when not in use and equilibrate to room temperature before application

Fluorescence microscopy compatibility

ProLong RapidSet Antifade Mountant hardens in one hour, with a 1.52 refractive index and maximum photobleaching protection. It is compatible with most fluorescence imaging systems and objectives, including epifluorescence, wide-field, confocal, and spectral.

ProLong RapidSet Antifade Mountant is designed for researchers seeking to streamline their imaging process without sacrificing quality or performance. Its rapid curing time, exceptional fluorophore protection, and compatibility with various imaging systems make it an essential tool for high-resolution fluorescence microscopy.
