Data from: Simultaneous and sensitive quantification of protein and low molecular weight persulfides, polysulfides, and H2S in biological samples

This work describes the development and validation of a high-sensitivity
analytical method (LC-MS/MS IAM-TPP) for the simultaneous quantification
of protein persulfides, low molecular weight persulfides/polysulfides and
hydrogen sulfide (H₂S) in complex biological matrices. The method was
applied to biological samples to characterise H2S and endogenous
persulfide/polysulfide formation, including analysis or physiologically
relevant ischemia reperfusion models. The raw dataset is intended to
enable independent re-analysis, method reuse, and further translational
development in redox biology and drug discovery.
