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.
6-Aminofluorescein has been demonstrated to be useful fluorescent labeling reagent for fullerene-based liposome nanostructures termed "buckysomes". 6-aminofluorescein dissolved in 0.1 N NaOH can be quantified from a maximum absorbance at 490 nm. Decarboxylated 6-aminofluorescein dissolved 6 N HCl (prepare by constant boiling at 110° C for 24 h) can be quantified from a maximum absorbance at 454 nm. Aldehyde groups are formed by oxidateive damage to proteins, which can be detected by conjugation to decarboxylated 6-aminofluorescein. 6-Aminofluorescein has been used to determine its ability to potentiate the antiviral activity of poly r (A-U).
