Electron Microscopy Sciences Citifluor Af1 + Dapi

Electron Microscopy Sciences Citifluor mounting medium for immunofluorescence is designed to reduce the fading of the fluorescence of dyes used for labeling biological specimens. In the technique of fluorescence microscopy, the fluorescence is stimulated by high intensity UV and/or visible light. Absorption of the light populates an excited state of the dye (usually a singlet state) and this leads to fluorescence. However, the excited state of the dye may undergo chemical reaction, which leads to destruction as evidenced by the fading of the fluorescence and consequent loss of the image. - EMS (Additional S&H or Hazmat Fees May Apply)
