Quality Control & Documentation
Biological Activity

H2DCFDA is a cell-permeable probe used to detect intracellular reactive oxygen species (ROS). H2DCFDA can be used for the Bacterial reactive oxygen species (ROS) production assay.

ROS Measurements

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.

Method measure the ROS levels
Cell Lines Each C. elegans strain
Concentrations 50 μM
Incubation Time 1 h
Results The results showed that CEO exposure made no significant difference to the GSH amount in each worm, however, the lipid peroxidation degree decreased due to the reduced ROS levels.

Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
