Description D-Luciferin potassium (D-Luciferin K Salt) is a luciferase (Luc) substrate that catalyzes the production of typical yellow-green light (560 nm) by bioluminescent insects. D-Luciferin potassium can be used in luciferase assays.
In vitro 方法:用于体外生物发光分析的 D-Luciferin potassium 的制备:1、用无菌水配制 200× D-Luciferin 储备液 (30 mg/mL),轻轻混匀,直到全部溶解。配制完成后可立即使用,也可分装储存于 -20℃。2、在预热的组织培养基中配制 1× D-Luciferin (150 µg/mL) 工作液。3、吸出培养细胞的培养基。4、在成像前向细胞中加入 1× D-Luciferin 溶液。成像前将细胞在 37℃ 下培养一小段时间可增加信号。
In vivo 方法:用于体内生物发光分析的 D-Luciferin potassium 的制备:1、用 DPBS 配制新鲜的 15 mg/mL D-Luciferin 储备液。用 0.20 um 过滤器过滤消毒。2、按小鼠体重注射 10 µL/g。每只小鼠应注射 150 mg D-Luciferin/kg 体重。例如,对于体重 10 g 的小鼠,注射 100 µL 以提供 1.5 mg D-Luciferin。3、在成像前 10-15 min 腹腔注射 D-Luciferin。应为每种动物模型进行荧光素动力学研究,以确定峰值信号时间。
