We designed and synthesized a series of 2’-deoxyribonucleoside triphosphates (dNTPs) bearing various lipid moieties. Fatty acid- and cholesterol-modified dNTPs proved to be substrates for KOD XL DNA polymerase in primer extension...
Correction for ‘Traceless enzymatic synthesis of monodispersed hypermodified oligodeoxyribonucleotide polymers from RNA templates’ by Marek Ondruš et al., Chem. Commun., 2022, 58, 11248–11251, https://doi.org/10.1039/D2CC03588J.
A modified 2′‐deoxycytidine triphosphate derivative (dCTOTP) bearing a thiazole orange moiety tethered via an oligoethylene glycol linker was designed and synthesized. The nucleotide was incorporated into DNA by DNA polymerases in vitro as well as in live cells. Upon incorporation of dCTOTP into DNA, the thiazole orange moiety exhibited a fluorescence lifetime that differed significantly from the non‐incorporated (i.e. free and non‐covalently intercalated) forms of dCTOTP. When dCTOTP was delivered into live U‐2 OS cells using a synthetic nucleoside triphosphate transporter, it allowed us to distinguish and monitor cells that were actively synthesizing DNA in real time, from the very first moments after the treatment. We anticipate that this probe could be used to study chromatin organization and dynamics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
