Special chemical components protect fluorescent dyes from fading (photobleaching) during fluorescence microscopy experiments, and delivers this protection without significantly quenching the initial fluorescence signal. ProLong Gold Antifade Mountant is a curing mountant that forms a near-perfect optical path (1.47 RI) and allows longer-term storage of the sample. Ready-to-use (room temperatures storage and no mixing required)-just apply a drop to the sample, add a coverslip, cure and image. ProLong Gold mountant is available with or without DAPI nuclear stain. ProLong Gold Antifade Mountant is for superior antifade protection of fluorescent proteins and fluorescent dyes, ProLong™ Diamond Antifade Mountant is recommended. Available with or without DAPI nuclear stain.

  • Protects dyes from fading during imaging
  • Ready-to-use liquid that cures for longer-term storage
  • Mounted samples are stable for months
  • Maintains fluorescence signal—little to no quenching
  • Ideal for Alexa Fluor™ dyes

  • Photobleaching protection without quenching
  • Stable signals during imaging and for longer-term storage
  • Refractive index matching without acrylic resins

Not recommended for mounting samples containing fluorescent proteins, such as GFP.
