Oxygen label
Tetrathiatriarylmethyl radicals are commonly used as oximetry labels for EPR imaging applications. The electronic properties and the ther-modynamic preferences for O2 addition to various radicals can be investigated using oxygen sensitive labels (patent pending).

(200µL of 200 µM solution to perform the analysis up to 400 samples)
