importance for the in-depth study of its virtual functional roles. However, the ER-targeting fluorescent probe for the detection of H2S in live cells is still quite rare. Herein, a new ER-targeting fluorescent probe (FER-H2S) for detecting H2S in live cells was characterized in the present study. This probe FER-H2S was built from the hybridization of three parts, including fluorescein-based skeleton
硫化氢(H 2 S)作为重要的信号生物分子,参与了一系列复杂的生理和病理过程。内质网(ER)中H 2 S水平的原位和快速检测对于深入研究其虚拟功能的作用非常重要。但是,用于检测活细胞中H 2 S的靶向ER的荧光探针仍然很少。在此,本研究中表征了一种用于检测活细胞中H 2 S的新型ER靶向荧光探针(FER-H 2 S)。该探针FER-H 2 S是通过三个部分的杂交构建的,包括基于荧光素的骨架,对甲苯磺酰胺为ER特异基团,2,4-硝基苯磺酸盐为对H 2 S的响应位点。探针FER-H 2 S对H 2 S的响应机理是基于开环和荧光素部分的开环过程。此外,探针FER-H 2 S已成功用于活细胞内质网中外源性和内源性H 2 S的成像。
