ReAsH-EDT2

ReAsH-EDT2 is a fluorescent, membrane-permeable biarsenical compound that binds covalently to tetracysteine sequences, which are engineered into target proteins. It binds proteins that have the tetracysteine tag almost immediately after translation. ReAsH-EDT2 is commonly used to study protein trafficking, folding, and interactions in living cells or cell lysates. This red-emitting fluorophore is excited at 593 nm, with emission at 608 nm.Formal Name: 4,6-bis(1,3,2-dithiarsolan-2-yl)-7-hydroxy-3H-phenoxazin-3-one. CAS Number: 438226-89-2. Synonyms: Lumio Red.
