Biotium launches mounting media with far-red nuclear counterstain and autofluorescence quenching reagent
Biotium, a leading provider of reagents for immunofluorescence microscopy, is significantly expanding its line of antifade wet-set and hardset EverBrite Mounting
Medium with options that include Biotium’s new far-red NucSpot 640 nuclear counterstain. In addition, Biotium is also releasing EverBrite TrueBlack Hardset Mounting Medium for mounting and quenching of lipofuscin autofluorescence in a single step.
Antifade mounting media, like EverBrite, typically includes DAPI as a convenient blue nuclear counterstain for researchers performing immunofluorescence microscopy. However, cross-talk between fluorescence channels and UV-induced photoconversion of DAPI can cause bleed-through fluorescence in neighbouring FITC or Cy 3 channels. Biotium developed EverBrite Mounting Media with NucSpot counterstains as a novel solution to DAPI cross-talk and UV photoconversion, offering bright and specific nuclear imaging with very limited interference in other channels. EverBrite NucSpot 640 is specific for the Cy 5 channel.
Biotium’s TrueBlack lipofuscin quenchers are unique reagents designed to quench lipofuscin autofluorescence commonly found in human and aged animal tissues. New EverBrite TrueBlack Hardset Mounting Medium is the first reagent to offer both mounting and quenching of lipofuscin autofluorescence in a single step for greater convenience. EverBrite TrueBlack Hardset Mounting Medium will be available with DAPI, NucSpot 640, or without a nuclear counterstain.
This release adds to Biotium’s growing portfolio of novel reagents for immunofluorescence microscopy, offering innovative solutions for all user workflows. Biotium’s new EverBrite with NucSpot and EverBrite TrueBlack Hardset Mounting Medium will be available in a standard 10 mL size or 2 mL trial size. NucSpot 640 nuclear counterstain is currently available with EverBrite Hardset and EverBrite TrueBlack Hardset Mounting Medium.
