EverBrite™ mounting medium is a revolutionary antifade mounting medium optimally formulated for preserving fluorescence of Biotium's CF™ dyes and other fluorochromes. Unlike VectaShield®, EverBrite™ is compatible with cyanine-based fluorophores like Cy® dyes. The mounting medium permits immediate imaging of slides and tissues after sealing edges of coverslips with nail polish or Biotium’s CoverGrip™ Coverslip Sealant. After mounting, slides can be stored at 4°C for a year or longer. EverBrite™ provides a high level of protection from photobleaching over a wide range of fluorescence wavelengths. EverBrite™ Mounting Medium has a refractive index of 1.46, which is well-matched to the refractive indices of coverslip glass and immersion oil (1.5). 10 mL.
