Fluorescent Dye

Fluorescent dyes, also known as fluorophores or fluorescent probes, are compounds that absorb light at one wavelength and emit it at a higher wavelength, producing visible fluorescence. They are essential tools in biological research, used for labeling and detecting biomolecules such as proteins, nucleic acids, and cells, enabling sensitive and precise visualization in applications like microscopy, flow cytometry, and real-time PCR.
