Abstract:Two photo‐crosslinking biarsenical (CrAsH‐EDT2)‐modified probes were synthesized that are expected to be useful tools for tetracysteine‐labeled proteins to facilitate the co‐affinity purification of their DNA binding sequences and interacting proteins. In addition, improvements for the synthesis of CrAsH‐EDT2 and N
1‐(4‐azido‐2‐nitrophenyl)hexane‐1,6‐diamine are reported. Both photoprobes effectively entered HeLa cells (and the nucleus) and were dependent on the tetracysteine motif in recombinant DMRT1 (double… Show more
Though arsenic alone is acutely toxic, its incorporation into fluorescent probes renders it less harmful and enables multiple applications in life sciences. See how your research can be improved using biarsenical probes.
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.
