Rlyso, a highly selective and sensitive pH sensor, can stain lysosomes with a novel lysosome-locating group, methylcarbitol. Rlyso was successfully used to detect lysosomal pH changes during apoptosis or induced by chloroquine while avoiding the “alkalizing effect” on lysosomes of current lysosomal probes with nitrogen-containing sidechains.
Rlyso是一种高度选择性和敏感的pH传感器,可以用新型的溶酶体定位基团—甲基醇来染色溶酶体。Rlyso成功地用于检测细胞凋亡过程中或氯喹诱导下的溶酶体pH变化,同时避免了当前含氮侧链的溶酶体探针对溶酶体的“碱化效应”。
