functions. Due to its relatively low concentration, it is still a great challenge to specifically track the basal HOCl in normal cells. In this paper, based on the unique chlorination of HOCl by the initiation of chlorinium ions (Cl+) in an acidic medium, we have developed a simple pH-mediated lysosome-targetable fluorescent probe Lyso-HOCl for the specific detection of HOCl over other bioactive molecules at
在亚细胞
水平上检测HOC1的技术的发展对于阐明其细胞功能非常重要。由于其相对较低的浓度,在正常细胞中特异性追踪基础HOCl仍然是巨大的挑战。在本文中,基于通过在酸性介质中引发
氯离子(Cl +)对HOCl进行独特的
氯化作用,我们开发了一种简单的pH介导的可溶酶体靶向的荧光探针Lyso-HOCl,可以特异性检测HOCl而不是其他
生物活性物质。浓度较高(500μM)的分子。我们的结果表明,Lyso-HOCl的检出限为8.0 pM,可以定量检测皮摩尔级的HOCl。
