3' 2-Aminopurine

Return to Modified Bases Modifications

2-Aminopurine can substitute for dA in an oligonucleotide. It is a naturally fluorescent base that is sensitive to the local environment making it a useful probe for monitoring the structure and dynamics of DNA hairpins and for detecting the base stacking state of a duplex. 2-Aminopurine can be destabilizing and slightly lower the Tm.
