Autofluorescence and induced fluorescence in Epon embedded tissue sections.

P del Castillo, M L Molero, J M Ferrer

    Histochemistry
    |January 1, 1986

    Summary

    Tissue autofluorescence in Epon sections varies with excitation wavelength, thickness, and observed structures. Understanding this autofluorescence is crucial for accurate interpretation of fluorescence microscopy results in Epon sections.
