A ratiometric fluorescent dye for detection of Lys and Arg and its bioimaging in live cells and zebrafish larvae

摘要

A ratiometric and pH-sensitive fluorescent dye named IDE was applied to the detection of argine and lysine from common amino acids and exploited to monitor the Lys and Arg levels in living cells and zebrafish larvae successfully. IDE will be a useful fluorescence indicator of pH changes by Lys and Arg.
