Background:

PSP is a two-photon fluorescent probe for hydrogen polysulfide (H₂S_n), a reactive sulfur species (RSS) formed during ferroptosis.¹Upon reaction with H₂S_n, the 2-fluoro-5-nitro-benzoate quenching group of PSP is removed, resulting in the release of a near-infrared emitting product. PSP is selective for H₂S_nover a panel of reactive oxygen species (ROS), reactive nitrogen species (RNS), metal ions, and sulfur-containing ions. It has been used to detect H₂S_nin live cells and tumor spheroidsin vitro.
