Fluorescamine is an organic spiro compound that is used in protein analysis .
Fluorescamin is used for fluorescent labeling of amino acids , peptides , sulfonamides and proteins in the picomole range for chromatography and gel electrophoresis . A "free" amino group is derivatized with the reagent:
Fluorescamine shows no fluorescence without derivatisation, the derivative can be excited at 390 nm and then emits at 475 nm. The fluorescence optimum is at pH 9 and fluorescamine is not stable in aqueous solution, so the method is not widely used.
