Product Description: 2-Aminopurine dihydrochloride is a fluorescent analog of guanosine. 2-Aminopurine dihydrochloride can be used as a fluorescence probe for nucleic acid structure and dynamics. Incorporating 2-Aminopurine dihydrochloride into DNA quenches its fluorescence[1][2].
Formula: C5H7Cl2N5
