| Bioactivity | LysoTracker Red is a Red fluorescently labeled lysosomal probe with a maximum excitation/emission wavelength of 577/590 nm. The structure is composed of a fluorescein group and linked weak bases, which can freely cross the cell membrane and gather on spherical organelles. It is suitable for observing the internal biosynthesis and related pathogenesis of lysosomes[1]. | ||||||||||||
| Invitro | 1.工作液配制：1.1 将溶液恢复至温室温，瞬时离心使其集中至管底。1.2 利用培养基或合适的缓冲液 (如PBS) 将 1 mM 储存液稀释至工作浓度，推荐工作液浓度为 50-100 nM；注：请根据实际情况调整 LysoTracker Red 工作液浓度，且现用现配。2.细胞染色2.1 悬浮细胞：离心收集细胞，加入 PBS 洗涤两次，每次 5 分钟。贴壁细胞：弃去培养基，加入胰蛋白酶消化细胞。离心弃去上清后，加入 PBS 洗涤两次，每次 5 分钟。2.2 加入 1 mL LysoTracker Red 工作液，室温孵育 5-30 分钟。2.3 400 g，4℃ 离心 3-4 分钟，弃去上清。2.4 加入 PBS 洗涤细胞两次，每次 5 分钟。2.5 用 1 mL 无血清培养基或 PBS 重悬细胞后，在荧光显微镜或流式细胞仪下检测。 | ||||||||||||
