Reversible Fluorescent Fe3+ Sensor (RPE)

RPE is a highly selective, sensitive and reversible off-on fluorescent Fe3+ sensor which can selectively image native Fe3+ in live cells.

Highlights:

  • Allows for viewing of endogenous exchangeable Fe3+ pools at sub-cellular resolution
  • Unique reversible "turn-on" property and high sensitivity
  • Little interference from other biologically relevant metal ions

RPE is a highly sensitive, highly selective and reversible turn-on fluorescent Fe3+ sensor. The sensor readily detects endogenous chelatable Fe3+ in live human SH-SY5Y cells at subcellular resolution in real time. The sensor gives a distinct rapid and reversible fluorescence response upon the alteration of intracellular Fe3+ levels with little interference from other biologically relevant metal ions.
