Bioactivity KMG-301AM TFA is the acetoxy methyl esterified form of KMG-301. KMG-301AM TFA successfully accumulates in mitochondria and then it is hydrolyzed to KMG-301. KMG-301 is an Mg2+-selective fluorescent probe functional in mitochondria in intact cells. Since the mitochondrial membrane is impermeable to KMG-301, it is not released upon depolarization of the mitochondrial membrane potential. KMG-301 can indicate changes in mitochondrial Mg2+ concentration and shows Mg2+ transport across the mitochondrial membrane in the early phases of a cellular model[1].
Invitro 实验方案:本方案仅提供一个指导,应根据您的具体需要进行修改[1]。1、对于光学成像,将 20 µM KMG-301AM TFA 与 Hanks 平衡盐溶液 (HBSS) 中的细胞一起孵育,在冰上放置 10 分钟,以避免细胞质中存在的酯酶水解乙酰氧基甲酯。HBSS 包含 (mM):NaCl,137:KCl,5.4;CaCl2,1.3;MgCl2,0.5;MgSO4,0.4;Na2HPO4,0.3;KH2PO4,0.4;NaHCO3,4.2;D-glucose,5.6;HEPES,5 (用 NaOH 将 pH 调节至 7.4)。2、用 HBSS 洗涤细胞两次,并在 37°C 下孵育 15 分钟,以使线粒体中的乙酰氧基甲酯形式完全水解。3、如果您想同时使用 KMG-104AM (HY-128536) 和 KMG-301AM TFA,请将细胞与 5 µM KMG-104AM 在 HBSS 中于 37°C 孵育 30 分钟,然后用 KMG-301AM TFA 染色。4、将分离的线粒体与 20 µM KMG-301AM TFA (溶于线粒体成像缓冲液 (MIB)) 在 37°C 下孵育 20 分钟。然后用 MIB 洗涤线粒体两次,并在 37°C 下进一步孵育 15 分钟。MIB 包含 (mM):KCl,125;K2HPO4,2;MgCl2,1;HEPES,5;EDTA,0.02 (用 KOH 将 pH 调节至 7.2) 或不含 Mg2+ 的 MIB (不含 MgCl2)。5、使用共焦激光扫描显微镜系统进行荧光成像实验。KMG-301 由激光二极管在 559 nm 处激发,并在 600-700 nm 处观察信号。在双染色中,KMG-104 和 KMG-301 分别在氩激光的 488 nm 和 559 nm 处被激发。使用 560 nm 二向色镜分离荧光并分别在 500-545 nm 和 600-700 nm 处观察。 MCE has not independently confirmed the accuracy of these methods.
