Fluorescein Dyes: Definition, Structure, Synthesis and Uses
2024-10-07
Fluorescein, a synthetic organic compound, has become an indispensable tool in biological research due to its fluorescent properties. Its bright green fluorescence under ultraviolet or blue light makes it ideal for various labeling applications in cell biology, molecular biology, and immunology. The versatility of fluorescein and its derivatives, particularly fluorescein isothiocyanate (FITC), allows for the specific labeling of cells, proteins, antibodies, and nucleic acids, providing crucial insights into the structure and function of biological systems.
Rhodamine Dyes: Definition, Structure, Uses, Excitation and Emission
2024-10-07
Rhodamine is an important class of flavonoid dyes. Due to its extended π-conjugated system, its open form exhibits strong fluorescence. They are used as laser dyes and in studies for detecting polymer and oligonucleotide adsorption. Dendritic polymers containing rhodamine as one of their components may have potential applications in materials science. Rhodamine dyes are used as fluorescent labeling reagents in biology because of their excellent optical properties, such as high fluorescence quantum yield, long excitation wavelength, and high photostability.
