基本介绍:

DAF-FM Diacetate(DAF-FM 双乙酸盐)是一种用于对细胞中的低浓度氧化亚氮进行定量的重要试剂。 在细胞内,非特异性酯酶可切割乙酸基。 生成的 DAF-FM 在与 NO 反应形成能发出荧光的苯并三氮唑之前,几乎没有荧光。495/515 nm 分别为最大激发/发射波长,因此可使用检测荧光素的任何仪器来检测 DAF-FM。

Method.Assessment of nitric oxide production(评估一氧化氮的产生)

DAF-FM diacetate (D23844, Invitrogen) was used to quantify NO production.At 80% confluence, cells were treated for 16h with GDF15 (50 ng/mL) or LPS (100 ng/mL) then washed and incubated with 1 μM DAF-FM diacetate probe in EBM2 + 0.5% FBS for 1h at 37°C. After removing the supernatant, cells were incubated in fresh EGM2 medium for 5 min at 37°C, resuspended in 1X PBS + 0.5% BSA and fluorescence intensity at 530 nm was quantified using Accuri C6 cytometer (BD Biosciences).
