Description and Uses

6-Aminofluorescein (6-AF) is a new fluorescence dye with bright colors and high fluorescence intensity. Its chemical structure history contains a nitrogen group and a fluorescent group. The presence of the fluorescent component enables 6-Aminofluorescein to emit a distinct fluorescent signal when excited, making it valuable for fluorescent labeling and imaging. It is widely used in biological science research, chemical analysis and fluorescence microscopy.

Fluorescent labeling reagent for proteins. Glycosaminoglycuronans react with 6-aminofluorescein to yield fluorescent derivatives. Used in the fluorescent antibody technique for rapid identification of pathogens.
