4、s is about 67 times larger than that in embryonic stem cells (ESCs). Both H2DCFDA and1/2 Master of Small Molecules 您邊的抑制劑師www.MedChemEDCFDA probes are non-fluorescent in their initial form but they undergo multistep conversion inside the cellthat results in the formation of fluorescent product dichl

5、orofluorescein (DCF). The only difference betweenthese two probes is that the conversion of H2DCFDA involves oxidation. Therefore, fluorescence of theH2DCFDA-treated cells depends on the intracellular ROS level, in contrast to fluorescence associated withthe DCFDA probe. Surprisingly, flow cytometry

6、 analysis shows that the difference between fluorescencelevels of ESCs and difESCs loaded with H2DCFDA is close to the difference between the signals fromDCFDA-treated cells. The latter indicates a ROS-independent reason for low fluorescent signal of oxidizedH2DCFDA in ESCs 1.PROTOCOLKinase Assay RO

7、S Measurements 1For the detection of intracellular ROS level ,ROS-sensitive probe H2DCFDA is used. Adherent cells (ESCs,difESCs, eMSCs, HeLa, U118) are incubated with 5 M staining solution in PBS in the dark for 30 min at37C, then harvested with 0.05% trypsin-EDTA solution, suspended in a fresh medi

8、um, and immediatelyanalyzed with flow cytometer. Lymphocytes, both control and PHA-activated, are resuspended in PBS,incubated with 5 M of H2DCFDA in the dark for 30 min at 37C, and immediately analyzed. Along with theH2DCFDA probe, if indicated, ROS-insensitive modification of the fluorescent dye D

9、CFDA is used. Thestaining procedure is the same as for the H2DCFDA 1.MCE has not independently confirmed the accuracy of these methods.
