    ROS Measurements[1]
    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].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
