Spin Traps, Spin Probes and Spin Labels

Santa Cruz Biotechnology now offers a broad range of Spin Traps, Spin Probes and Spin Labels. Spin labels introduce a stable radical moeity by binding functional groups chemoselectively, while spin traps and spin probes effectively capture transient radicals as a more stable species, allowing for structural and molecular environment elucidation by electron paramagnetic spectroscopy (EPS). Our popular products such as DEPMPO, 1-Oxyl-2,2,5,5-tetramethylpyrroline-3-carboxylate N-Hydroxysuccinimide Ester, and TOAC are typically available for immediate shipment.

indicates a highly recommended product based on customer preference.
