Bioactivity | Lucigenin is a chemiluminescence probe. Lucigenin can be used to detect the production of endogenous superoxide anion radical (O2-). Lucigenin is extremely sensitive to chloride ions, while it combined with chloride ions, the fluorescence will be quenched. Lucigenin also can be used as a chloride indicator. Ex/Em=455/505 nm[1]. |
Invitro | Lucigenin 工作液的配制1.1 制备储存液用 DMSO 配制 10 mM 的 Lucigenin。如用 0.1919mL DMSO 溶解 1 mg Lucigenin。注:Lucigenin 储存液建议分装后于 -20 ℃ 或 -80 ℃ 避光保存。1.2 工作液的配制用预热好的无血清细胞培养基或 PBS 稀释储存液,配制成 5-10 μM 的 Lucigenin 工作液。注:请根据实际情况调整 Lucigenin 工作液浓度,且现用现配。细胞染色2.1 准备工作悬浮细胞: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 Lucigenin 工作液,室温孵育 15 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,在荧光显微镜下检测。 |
