Background:

FlAsH-EDT2 is a pro-fluorescent, membrane-permeable biarsenical compound that binds covalently to a tetracysteine sequence (CCPGCC), which is engineered into target proteins.[1],[2] It binds proteins that have the CCPGCC tag almost immediately after translation.[2] FlAsH-EDT2 is commonly used to study protein trafficking, folding, and interactions in living cells or cell lysates.[2],[3],[4] This green-emitting fluorophore is excited at 508 nm, with emission at 528 nm.[4]
