Original EverBrite™ Mounting Medium

Biotium’s EverBrite™ line of mounting media are formulated to preserve fluorescence of our CF® Dyes and other fluorochromes. EverBrite™ comes in wet-set and hardset formulations, with and without nuclear counterstains. Drop-n-Stain EverBrite™ provides the wet-set EverBrite™ in a dropper bottle for easy dispensing.

Features
  • Antifade mounting medium optimally formulated to prevent photobleaching of fluorophores
  • Refractive index is well-matched to that of coverslip glass and immersion oil
  • Available in wet-set or hardset
  • Wet-set formulation available as convenient Drop-n-Stain EverBrite™
  • Available with DAPI, hardest formulation available with NucSpot® 640

EverBrite™ Hardset Mounting Medium with NucSpot®

Clearer Counterstaining in the Far-Red Channel

EverBrite™ Hardset with far-red NucSpot® 640 counterstain is an antifade medium that allows for one-step mounting and nuclear counterstaining. NucSpot® 640 is a far-red DNA binding dye for the Cy®5 channel that offers greater nuclear-specificity than the classic dye propidium iodide (PI) and avoids problems with cross-talk and photoconversion from DAPI.
Features
  • One-step mounting and nuclear counterstaining
  • Avoid issues of cross-talk and photoconversion from DAPI
  • Superior nuclear specificity compared to PI
  • Also available with EverBrite TrueBlack® Hardset

EverBrite TrueBlack® Hardset Mounting Medium

The all-in-one mounting medium

Lipofuscin are autofluorescent granules that are a common source of background that make fluorescence imaging virtually impossible in human and aged animal tissues such as brain and retina. EverBrite TrueBlack® Hardset Mounting Medium is the only mounting medium optimally formulated for quenching lipofuscin fluorescence while offering the same protection against photobleaching as our original EverBrite™ Hardset. The mounting medium is available without nuclear stain, with DAPI, or with NucSpot® 640 nuclear counterstains.

FAQs

EverBrite™ Mounting Medium (23001) and EverBrite™ Mounting Medium with DAPI (23002) both have a refractive index of 1.46.  EverBrite™ Hardset Mounting Medium (23003) and EverBrite™ Hardset Mounting Medium with DAPI (23004) both have an initial refractive index of 1.38, which increases to 1.42 after 24 hours of curing, and 1.46 after 4 days, after which it remains constant

Yes, EverBrite™ mounting media are compatible with a wide range of dyes. Unlike VectaShield®, EverBrite™ won’t interfere with cyanine-based fluorophores like Alexa Fluor® 647, Cy®3, or Cy®5.

EverBrite™ wet-set mounting medium is an aqueous, glycerol-containing medium. It can be removed from samples by washing several times with PBS or other buffer. However, washing with PBS will not remove DAPI staining.

For coverslips mounted on slides with EverBrite™ Hardset or EverBrite™ wet-set medium, the slides can be soaked in PBS in a slide jar for several hours with gentle agitation until the coverslip slides off (avoid prying or pulling the coverslip, which could damage the sample). Then wash the slide several times to remove any remaining mounting medium. If the coverslips have been sealed with CoverGrip™ Coverslip Sealant, soaking in PBS will remove the sealant as well. Other methods may be required to remove other types of coverslip sealants.
