NucPE1 (Nuclear Peroxy Emerald 1) is a nuclear-localized fluorescent hydrogen peroxide that is specifically localized to cellular nuclei without appended targeting moieties.
体外研究
NucPE1 features two major visible region absorptions (λabs=468 nm, ε=27,300 Mcm; λabs=490 nm, ε=26,000 Mcm) and a weak emission (λem=530 nm, Φ=0.117). Reaction of NucPE1 with H2O2 triggers a fluorescence increase upon its conversion to fluorophore NucPE1, which possesses one major absorption band at 505 nm (ε=19,100 Mcm) with enhanced emission (λem=530 nm, Φ=0.626). NucPE1 selectively accumulates in the nuclei of a variety of mammalian cell lines as well as in whole model organisms like C. clegans, where it can respond to subcellular changes in H2O2 fluxes.
体内研究
NucPE1 maintains the ability to selectively target nuclei in vivo. NucPE1 imaging reveals a reduction in nuclear H2O2 levels in worms overexpressing sir-2.1 compared to wildtype congeners, supporting a link between this longevity-promoting sirtuin protein and enhanced regulation of nuclear ROS pools.
