CPH
Effective, partially cell permeable and non-toxic spin probe for the detection in vitro
and in vivo of superoxide radical and other reactive oxygen species such ONOO-.
The spin adduct is resistant to reduction by vitamin C and thiols. Half-life time of spin
 adduct in biological environment amount to 4h. Samples in frozen condition
(-80 °C or liquid nitrogen) can be stored up to 6 months.
