Solution:
In amino acid composition analysis, amino acids are visualized after separation using the chemical reagent isfluorescamine.
Non- fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Low background due to hydrolysis. Useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes. Effectively blocks newly generated amino termini in protein sequence analyses.
The right answer is fluorescamine.
