eFluor^® Nanocrystals can easily be used to detect specific antigens by microscopy. They are suitable for immunofluorescent staining of cultured cells and frozen or paraffin embedded tissue samples. Using eFluor^® Nanocrystals for immunofluorescence rather than conventional organic dyes allows you to take advantage of their inherent photostability.

This means that once tissue is stained, the signal will be stable for significantly longer than the signal provided by other more photo-labile dyes. In addition, the broad excitation and narrow emission spectra of eFluor^® Nanocrystals enables multicolor analysis of samples.
