Abstract

The high reactivity of thiyl radicals (RS(•)), which results in half-lives on the order of microseconds, hinders their analysis in biological systems. This Feature reviews the contemporary approaches to assessment of RS(•) using EPR spin trapping, mass spectrometric, immunological, and HPLC protocols.

摘要

硫自由基(RS(•))的高反应性导致其半衰期约为微秒级,这阻碍了它们在生物系统中的分析。本专题综述了使用 EPR 自旋捕获、质谱、免疫和 HPLC 方案评估 RS(•)的现代方法。
