DescriptionLightner and co-workers1-3 reported the synthesis and spectroscopic properties of fluorophores based on the 3a,4a-diazaindacene ring system ("xanthglows"). Key properties include a high quantum yield (>0.9) and a large Stokes shift (>100 nm). Berry & Associates offers an amine-reactive version, Diazaindacene NHS Ester, for incorporation of the diazaindacene fluorophore into biomolecules. Download Product Information. Spectroscopic properties: The absorption maximum of the corresponding carboxylic acid is reported to be 425 nm in methanol, extinction coefficient = 15,300. The emission maximum of the carboxylic acid is 535 nm in methanol with a quantum yield of 0.91.1 When installed onto a 5'-amino-modified oligonucleotide,4 the absorption and emission maxima appear at 430 nm and 530 nm, respectively, in aqueous MgCl2/KCl/Tris-HCl (pH 8.0). For comparison, an analogous TET-labeled oligonucleotide showed absorption and emission maxima at 522 nm and 538 nm, respectively. 1. Brower, J. O.; Lightner, D. A. J. Org.
