APF是用于检测高活性氧(hROS)的荧光试剂(λ| Ex | max |:490nm;λ| Em | max |:515nm)。立即与hROS(例如氢氧根,过亚硝酸盐和次氯酸盐)反应,荧光强度大大提高。当将APF与HPF一起使用时,还允许对次氯酸盐(|-| OCl)进行特定检测,以阐明|-| OCl在生物系统(如嗜热性粒细胞)中的可靠作用。由于APF不会与一氧化氮,超氧化物和过氧化氢反应,因此还可以检测出过氧化亚硝酸盐与一氧化氮和超氧化物的区别。APF抵抗光诱导的自氧化
APF is a fluorescent reagent (λ|Ex|max|: 490nm; λ|Em|max|: 515nm) used in the detection of highly reactive oxygen species (hROS). Immediately reacts with hROS such as hydroxyl radical, peroxynitrite and hypochlorite, and the fluorescence intensity greatly increases. When using APF together with HPF, it also allows for specific detection of hypochlorite (|-|OCl) to elucidate reliable roles of|-|OCl in biological systems such as netrophils. Peroxynitrite can also be detected in distinction from nitric oxide and superoxide since APF does not react with nitric oxide, superoxide and hydrogen peroxide. APF is resistant to light-induced autooxidation
Prepare 500-5'000-fold dilution (~10-1µM) in phosphate buffer (0.1M phosphate, pH 7.4) immediately before use. BSA, phenol red and amines may affect the fluorescence and must be used with caution. Do not store the dilutions.", '
