EPR (Electron Paramagnetic Resonance) is the only direct measurement method for reactive oxygen species. This phenomenon was discovered by the Russian physicist Zavoisky, and it allows for the measurement of reactive oxygen species and antioxidant capacity in various situations and states. Furthermore, we can create and measure protocols tailored to your needs, so please feel free to consult with us.

"Quantitative measurement of reactive oxygen species" allows for the evaluation of the amount of reactive oxygen species. By generating the reactive oxygen species to be measured and using the spin-trap method, the signal intensity (magnitude of the wave) is compared between the control and the sample. This enables the measurement of the antioxidant capacity of the sample. 【Features】 ■ Ability to evaluate the amount of reactive oxygen species ■ Measurement using the spin-trap method *For more details, please contact us or download the catalog.

The "Spin Labeling Method / Spin Probe Method" is a technique that binds a stable reactive oxygen species label to target molecules to measure spectra and analyze molecular information around reactive oxygen species. In vivo, it can be administered as a probe, allowing for the measurement of the dynamics of radicals in the body and antioxidant capacity from the attenuation of its signal intensity. Additionally, it is possible to visualize data using ESR-CT. 【Features】 ■ Binding of the label to target molecules ■ Measurement of spectra ■ Analysis of molecular information around reactive oxygen species *For more details, please contact us or download the catalog.

The "Spin Trap Method" is an analytical technique used to identify which reactive oxygen species are present. It captures unstable reactive oxygen species with a spin trap reagent and converts them into more stable radical species (spin adducts) for analysis. The spectra obtained for each reactive oxygen species differ, allowing for the identification (qualitative analysis) of the reactive oxygen species. 【Features】 ■ Capable of distinguishing types of reactive oxygen species ■ Converts to stable radical species (spin adducts) for analysis *For more details, please contact us or download the catalog.
