Description

Coppersensor 1 is a fluorescent sensor for selective and sensitive detection of copper(I) ions (Cu+) in biological samples, including live cells, with an excitation wavelength of 543nm and an emission wavelength of 576nm[1]. Coppersensor 1 comprising a boron dipyrromethene (BODIPY) chromophore coupled to a thioether-rich receptor, has a picomolar affinity for Cu+ with high selectivity over competing cellular metal ions. CS1 fluorescence increases up to 10-fold on binding to Cu+[2]. Copper is the third most abundant transition metal after iron and zinc, which plays a crucial role in the biological system as it is a cofactor of various human enzymes for pigment production, antioxidant, defense, and other metabolism[3]. Excess copper ions can generate reactive oxygen species (ROS) that damage bio-molecules like proteins, nucleic acids, and lipids, leading to liver, kidney, and digestive disorders, whereas insufficient copper ion intake can lead to metabolic disorders of the brain and nervous system[4][5]. Coppersensor 1 can be applied in the research of cancer, antibacterial mechanisms, and neurodegenerative diseases[6-8].

Coppersensor 1是一种选择性灵敏检测生物样品(包括活细胞)中铜(I)离子(Cu+)的荧光传感器,激发波长543nm,发射波长576nm[1]。Coppersensor 1由一个硼二吡咯亚甲基(BODIPY)发色团与富含硫醚的受体耦合而成,对Cu⁺具有皮摩尔级亲和力,且在细胞内众多金属离子中对Cu⁺具有高选择性。当与Cu⁺结合时,CS1的荧光强度可增加高达10倍[2]。铜是铁和锌之后的第三大丰富过渡金属,在生物体系中发挥着关键作用,因为它是多种人类酶的辅因子,参与色素生成、抗氧化防御以及其他代谢过程[3]。过量的铜离子会生成活性氧(ROS),从而损伤蛋白质、核酸和脂质等生物分子,导致肝脏、肾脏和消化系统疾病,而铜离子摄入不足则会导致大脑和神经系统代谢紊乱[4][5]。Coppersensor 1可用于癌症、抗菌机制和神经退行性疾病的研究[6-8]

实验参考方法

以下是我们推荐的方案。该方案仅提供指南,应根据您的具体需求进行修改[1]

1. 制备用于成像的试剂储备溶液:

(1)通过在每毫升 DMSO 溶剂中溶解 0.63mg 固体Coppersensor 1,在 DMSO 中制备 1 mM Coppersensor 1储备溶液(MW 630g/moL)。

2. 活细胞的Coppersensor 1标记:

(1)细胞成像实验需要培养 1-2 天。根据您的正常方案孵育细胞。

(2)在成像前一天,将细胞传代并置于涂有聚-L-赖氨酸(50μg/mL)的 18mm 玻璃盖玻片上。用于成像的贴壁细胞生长至 50-80% 融合。

(3)从培养箱中取出细胞,将一个盖玻片转移到含有 3mL PBS 缓冲液的 35mm培养皿中。

(4)向培养皿中加入 15μL 1mM Coppersensor 1原液,使染料最终浓度为 5μM。充分混合。(染料浓度越高,背景荧光水平越高)

(5)在 25 或 37℃ 的黑暗环境中孵育 5-20 分钟。

3. 对 Coppersensor 1 标记细胞进行成像:

(1)在标准共聚焦显微镜下成像,激发波长为 543nm,发射波长为 576nm。(Coppersensor 1可以使用任何类型的荧光显微镜进行成像,包括落射荧光、共聚焦和多光子)

注意事项:

①建议设置阳性对照,对照组细胞使用30μM油酸孵育8小时后进行后续实验;

②荧光染料均存在淬灭问题,请尽量注意避光,以减缓荧光淬灭;

③为了您的安全和健康,请穿实验服并戴一次性手套操作。
