| 生物活性 |
Hydroxyphenyl fluorescein (HPF) is the reagent that can directly detect highly reactive oxygen species (hROS). Hydroxyphenyl fluorescein selectively and dose-dependently reacts with hROS, such as the hydroxyl radical and peroxynitrite, which exhibit strong fluorescence[1][2]. |

| 体外研究 (In Vitro) |
The fluorescence of Hydroxyphenyl Fluorescein (HPF) is greatly enhanced following incubation with blue light illuminated blebbistatin (30 min). Fluorescence enhancement of Hydroxyphenyl Fluorescein occurred equally efficiently under Ar purged and non-Ar purged conditions, suggesting that singlet oxygen as an intermediate involved is improbable. Fluorescence measurement with Hydroxyphenyl Fluorescein suggests a negative linear relationship between fluorescence intensity of Hydroxyphenyl Fluorescein (10 μM) and thiourea concentration (0-1 mM)[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
| 体内研究 (In Vivo) |
The Hydroxyphenyl Fluorescein (HPF) probe (15 μl, 25 μM) is given intratesticularly in anaesthetized mice 20 min before IR (ionizing radiation). The accumulation of •OH by the fluorescence signal emitted by the oxidized form of HPF is assessed[3]. MCE has not independently confirmed the accuracy of these methods. They are for reference only. |
