2-Aminopurine;(Synonyms: 2-氨基嘌呤) 纯度: 99.53%

2-Aminopurine 是鸟苷和腺苷的荧光类似物，是一种广泛使用的基于荧光衰变的 DNA 结构探针。当将 2-Aminopurine 插入寡核苷酸时，其荧光会通过与天然碱基堆积而被高度淬灭。2-Aminopurine 已被用于探测核酸的结构和动力学。

生物活性

2-Aminopurine, a fluorescent analog of guanosine and adenosine, is a widely used fluorescence-decay-based probe of DNA structure. When 2-Aminopurine is inserted in anoligonucleotide, its fluorescence is highly quenched by stacking with the natural bases. 2-Aminopurine has been used to probe nucleic acid structure and dynamics[1][2].

体外研究
(In Vitro)

2-Aminopurine (2AP) is not valuable as afluorescent label because its fluorescence is highly quenched by stacking with the natural bases, when it is inserted in anoligonucleotide. However, it is this very susceptibility to interbase quenching that makes 2AP an exquisitely sensitivefluorescent probe of nucleic acid structure[1].
2-Aminopurine differs from adenine (6-aminopurine) only in the position of the exocyclic amine group, and yet its fluorescence intensity is one thousand times that of adenine[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
