ProLong® Diamond Antifade Mountant is a glycerol-based liquid mountant applied directly to fluorescently labeled cells or tissue samples on microscope slides. ProLong® Diamond mountant is designed to provide unparalleled antifade protection across the entire visual and IR spectrums. You can use ProLong® Diamond mountant with almost any fluorescent dye or fluorescent protein (e.g., GFP, RFP, mCherry) to achieve the brightest signal and lowest background, for bright, high definition fluorescent images.

Features of ProLong® Diamond Antifade Mountant include:
• Protects fluorescent dyes and fluorescent protein from fading, across entire visible and IR spectrums
• Ready-to-use liquid that cures for longer-term storage
• Ideal for Alexa Fluor® and traditional dyes, such as FITC and Cy®3, and fluorescent proteins like GFP, RFP, and mCherry• Mounted samples are stable for months
• Maintains fluorescence signal—little to no quenching

ProLong® Diamond Antifade Mountant comes already mixed and ready to use in a dropper bottle, with or without DAPI. Just apply a drop to the sample, add a coverslip, cure, and image. ProLong® Diamond mountant is a curing mountant that forms a near-perfect optical path (1.47 RI) and enables longer-term storage of your samples, while protecting them from photobleaching. ProLong® Diamond mountant does not discolor or shrink when cured and stored long term, making it possible to take high quality fluorescent images weeks or even months after mounting the slides.
