Cayman 2-Aminopurine (Hydrochloride); Purity- Greater Than Or Equ

2-Aminopurine is a fluorescent analog of guanosine and adenosine that is used as a site-specific probe of nucleic acid structure and dynamics.¹ It base pairs with cytosine in a wobble configuration or with thymine in a Watson–Crick geometry.¹ In addition to its usefulness in studies of base stacking interactions, 2-aminopurine has been used as a probe for DNA base flipping by methyl transferases.² 2-Aminopurine exhibits an excitation/emission of 320/381 nm, respectively, when adjusted to reduce interference with DNA base absorption as well as tryptophan fluorescence.² 2-Aminopurine inhibits the double-stranded RNA-dependent protein kinase, protein kinase R, whose activity mediates antiviral defense and participates in toll-like receptor signaling.³
