Description: 2-Aminopurine dihydrochloride, a fluorescent analog of guanosine, serves as a fluorescence probe for analyzing nucleic acid structure and dynamics. When incorporated into DNA, it exhibits quenched fluorescence [1] [2]. For storage, it should be protected from light. Smiles: Cl.Cl.Nc1ncc2[nH]cnc2n1

2-Aminopurine is a fluorescent analog of guanosine and adenosine that is used as a site-specific probe of nucleic acid structure and dynamics. It base pairs with cytosine in a wobble configuration or with thymine in a Watson-Crick geometry. In addition to its usefulness in studies of base stacking interactions,...
