2-Aminopurine, a purine analog of guanine and adenine, is a fluorescent molecular marker used in nucleic acid research.[1] It most commonly pairs with thymine as an adenine-analogue, but can also pair with cytosine as a guanine-analogue;.[2] For this reason it is sometimes used in the laboratory for mutagenesis.
