Spin trapping reagent

Most efficient spin trap for the in vitro and in vivo detection of O-, N-, S- and C-centered free radicals. Has a longer life-time than DMPO (Prod. No. ALX-430-090). Can distinguish between superoxide-dependent and independent mechanisms that lead to the hydroxyl radical. Less lipophilic (Kp=0.16) than DIPPMPO (Prod. No. ALX-430-119).

Shipping: Available products typically ship within 24/48h, via priority shipping.
