BMPO is a cell-permeable superior spin trap that captures OH and O2•−, forming stable BMPO/OH and •BMPO-OOH adducts[1]. Using BMPO, the conversion of BMPO-OOH to BMPO-OH in the presence of glutathione (GSH) can be detected[2]. BMPO has been widely used for detecting the superoxide produced by the nitric oxide synthase (NOS) in neurons[3].

Evaluation of hydroxyl radicals using BMPO
This protocol only provides a guideline and should be modified according to your specific needs
1. Stock and working solution preparation
(1) Prepare BMPO stock solution (100mM) by dissolving BMPO powder in DMSO, which was then aliquoted into appropriate volumes and stored at -20°C.
(2) Dilute the BMPO stock solution with phosphate buffer to a final 30mM working solution.
NOTE: The working solution must be prepared fresh on the day of the experiment.
2. Electron paramagnetic resonance (EPR) Study of the BMPO-Adducts
(1) BMPO-OOH was prepared by the addition of the saturated KO2/DMSO solution (10% v/v DMSO/final buffer) to the BMPO (30mM final concentration; 37°C) diluted in the phosphate buffer.
(2) The BMPO/KO2 sample was mixed for 10s and then the studied compounds, H2Sn, SeOn2− or H2Sn/SeOn2− mixtures, were added. The sample was mixed again for 5s and transferred to a standard cavity aqueous EPR flat. The first EPR spectrum was recorded 100s after the addition of the compounds. The sets of the individual EPR spectra of the BMPO spin-adducts were recorded as 15 sequential scans, each 42s, with a total acquisition time of 11min. Each experiment was repeated at least twice.
3. Experimental Precautions
(1) This protocol and all reagents are for scientific research use only.
(2) For your safety and health, please wear a laboratory coat and put on disposable gloves when operating.
