Fluorescent dyes are compounds that absorb light at a specific wavelength and emit it at a longer wavelength. These properties make them highly valuable for histological studies, where they are used to label and visualize specific structures within biological tissues. Fluorescent dyes are essential for techniques such as immunofluorescence, where they can bind to antibodies targeting specific antigens, allowing researchers to observe the distribution and localization of proteins, nucleic acids, and other molecules.
