variety of physiology and pathological processes in vivo. Lysosomes are considered to be cleaners of living cells and play a vital role in the process of metabolism. Exposure to excess SO2 will result in the increase risk of lysosomal dysfunction and induce multiple diseases. Herein a smart fluorescent probe LYSO-SO2 is developed, which achieved the ratio (F561 nm/F634 nm) identification of SO2 in vitro
二氧化硫(SO 2)作为一种常见的环境污染物,在体内参与多种生理和病理过程。溶酶体被认为是活细胞的清洁剂,在新陈代谢过程中起着至关重要的作用。暴露于过量的SO 2将导致溶酶体功能障碍的风险增加,并诱发多种疾病。本文智能荧光探针LYSO-SO 2开发,实现了比(F 561纳米/ F 634纳米SO的)标识2 体外。溶菌素2具有高灵敏度(检测限15.8 nM),快速响应(5秒内)和出色的选择性。此外,该探针LYSO-SO 2已成功应用于溶酶体中SO 2的比率监测,这可能为研究活细胞中SO 2的生理和病理功能提供有效的定量方法。
