Description
ProLong Glass Antifade Mountant is a glycerol-based, hard-setting, ready-to-use mountant that can be applied directly to fluorescently labeled cells or tissue samples on microscope slides or coverslips. It is formulated without DNA stain or with the blue DNA stain NucBlue (Hoechst 33342) or with the deep red DNA stain SYTOX Deep Red. Prolong Glass mountant has a refractive index of 1.52 after curing, similar to that of glass coverslips, compatible immersion oil, and oil-immersion microscope optics, enabling superior resolution and sensitivity. ProLong Glass mountant is also designed to provide unparalleled photobleach protection across the visible and near infra-red spectra. You can use ProLong Glass Antifade Mountant with almost any fluorescent dye or fluorescent protein (e.g., GFP, RFP, mCherry) and with any cell/tissue type for image depths ranging from 0 to 100 μm for bright, high-resolution Z-Stack, 3D, and 2D images. For a non-curing mountant with 1.52 refractive index, try SlowFade Glass Soft-set Antifade Mountant.
With its high refractive index of 1.52 and superior antifade formulation, ProLong Glass Antifade Mountant delivers the following benefits:
• Up to 75% improvement in axial resolution for sharp images
• 3–4 times more imageable focal depth compared tomountants with refractive index of 1.47, with sharp images for monolayers of cells, tissue slices, or 3D cell cultures up to 150 μm thickness/focal depth
• Low background across the spectrum
• Preserved signals from inhibited photobleaching
• Weeks to months of stability for slide-mounted samples
• Ease of use
• Availability with or without DAPI
ProLong Glass Hard-set Antifade Mountant comes already mixed and ready to use in a dropper bottle or 10-mL bottle with or without DNA stain. NucBlue (Hoechst 33342) is excited by UV light at 360 nm when bound to DNA, with an emission maximum at 460 nm, and is detected using a DAPI traditional filter. SYTOX Deep Red stain is excited by red light at 660 nm when bound to DNA, with an emission maximum at 682 nm, and is detected using a Cy5/deep red traditional filter. After removing excess water, just apply a drop of mountant to the sample, add a coverslip, cure, and image. ProLong Glass mountant is a hard-setting, curing mountant that minimizes optical refraction and spherical aberration in the optical path, enables longer-term storage of your samples, and helps protect your samples from photobleaching. ProLong Glass mountant does not discolor or shrink when cured, making it possible to take high-quality fluorescent images weeks, or even months, after mounting the slides.
ProLong Glass Antifade Mountant with NucBlue stain contains an optimized concentration of Hoechst 33342 stain, which provides superior nuclear labeling of most cells and tissues. ProLong Glass mountant with NucBlue stain is not recommended for specimens thicker than 30 μm. Thicker specimens can require longer incubations with labeling reagents, so a pre-incubation with NucBlue Live ReadyProbes Reagent is recommended.
