Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. H2DCFDA is dissolved in DMSO to obtain a 10 mM stock solutions and further diluted before use.
2. Cells are incubated with 5 µM H2DCFDA solution in PBS in the dark for 30 min at 37°C, then harvested with 0.05% trypsin-EDTA solution, suspended in a fresh medium, and immediately analyzed with flow cytometer.
3. Along with the H2DCFDA probe, if indicated, use ROS-insensitive modification of the fluorescein dye DCFDA as a positive control. The staining procedure is the same as for the H2DCFDA[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

For the detection of intracellular ROS level ,ROS-sensitive probe H2DCFDA is used. Adherent cells (ESCs, difESCs, eMSCs, HeLa, U118) are incubated with 5 µM staining solution in PBS in the dark for 30 min at 37°C, then harvested with 0.05% trypsin-EDTA solution, suspended in a fresh medium, and immediately analyzed with flow cytometer. Lymphocytes, both control and PHA-activated, are resuspended in PBS, incubated with 5 µM of H2DCFDA in the dark for 30 min at 37°C, and immediately analyzed. Along with the H2DCFDA probe, if indicated, ROS-insensitive modification of the fluorescent dye DCFDA is used. The staining procedure is the same as for the H2DCFDA[1].

生物活性

DAF-2DA (5,6-Diaminofluorescein diacetat) is most widely probe for NO measurement.

体外研究
(In Vitro)

Nitric oxide is a free radical signal molecule. Various methods are available for measurement of NO. Out of all methods, fluorescent probes to localize NO is very widely used method. Diaminofl uorescein in diacetate form (DAF-2DA) is most widely probe for NO measurement. This method is based on application of 4,5-diaminofl uorescein diacetate (DAF-2DA) which is actively diffused into cells, once taken up by cells cytoplasmic esterases cleave the acetate groups to generate 4,5-diaminofl uorescein; DAF-2. The generated DAF-2 can readily react with N2O3, which is an oxidation product of NO to generate the highly fluorescent DAF-2T (triazolofl uorescein).

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Millipore密理博Ultrafree-DA离心超滤管

在单次 10 分钟离心操作中,可从琼脂糖凝胶条中回收 100bp 至 10,000bp 的 DNA。 该试剂盒包含预装好,带琼脂糖凝胶破碎管、微型离心管的过滤装置以及改良的 TAE 凝胶回收缓冲液(干剂)。

该装置通过压缩凝胶从琼脂糖中回收 DNA 。 离心力使凝胶结构破碎,将琼脂糖挤过凝胶破碎管的小孔变成浆状喷入样品过滤杯。

对于大多数应用,包括克隆、放射性或荧光 DNA 测序,所制备的 DNA 不需要进一步纯化。 因为琼脂糖凝胶电泳有很强的分离能力,PCR 之后产生的常常会干扰克隆或测序的大大小小的非特异性扩增产物就能完全去除

  • 手动时间少
  • 只需 10 分钟离心
  • 回收全功能 DNA

 

实验方案

1. 通过琼脂糖凝胶将 PCR 产物或其它 DNA 进行常规电泳分离之后,切下所需的条带。
2. 将凝胶条放入预先装好的装置。 注:此实验方案对于低熔点琼脂糖不适合。
3. 5,000xg 离心 10 分钟,胶条呈浆状喷入滤杯。
4. 将样品过滤杯和凝胶破碎管丢弃之后,可将 DNA 储存于带盖的滤过液管中。

测序图谱

用 Montage 凝胶回收试剂盒纯化 pUC18 凝胶片段后,再进行自动荧光测序的结果。 测序采用 ABI PRISM® Dye Terminator 测序即时反应试剂盒生成测序结果,此试剂盒含有 AmpliTaq DNA 聚合酶 (Applied Biosystems)。 测序结果的提供者为 Jeff McConnell,Director of Genomic Services,Cleveland Genomics,Cleveland,Ohio。
