Highly sensitive and specific fluorogenic probes to measure hypoxia and oxidative stress in live cells
Used with adherent or suspension cell lines
Complete set of reagents, including ROS and Hypoxia inducers
Enzo Life Sciences’ ROS-ID® Hypoxia/Oxidative stress detection kit is designed for functional detection of hypoxia and oxidative stress levels in live cells (both suspension and adherent) using fluorescent microscopy or flow cytometry. This kit includes fluorogenic probes for hypoxia (red) and for oxidative stress levels (green) as two major components.
The Hypoxia (Red) dye takes advantage of the nitroreductase activity present in hypoxic cells by converting the Nitro group to hydroxylamine (NHOH) and amino (NH2) and releasing the fluorescent probe.
The Oxidative Stress Detection Reagent is a non-fluorescent, cell-permeable total ROS detection dye which reacts directly with a wide range of reactive species. The generated fluorescent products can be visualized using a wide-field fluorescence microscope equipped with standard fluorescein (490/525 nm) and Texas Red (596/670 nm) filters, confocal microscopy, or cytometrically using any flow cytometer equipped with a blue (488 nm) laser.
Detection of hypoxia and oxidative stress levels in cultured human HeLa and HL-60 cells. Cells were treated with hypoxia inducer (DFO) and ROS inducer (pyocyanin). Numbers in each quadrant reflects the percentage of cells (population). Results indicate that hypoxia and oxidative stress dye are specific
HeLa cells were subject to treatment. Bright red fluorescence of the Hypoxia probe is observed following its conversion by cellular nitroreductases under hypoxic conditions such as those induced chemically by treatment with the hypoxia-mimetic desferrioxamine (DFO).
The absorption and emission peaks for the Oxidative Stress (A) and Hypoxia Red (B) detection dyes are 504nm/524nm and 580nm/595nm, respectively. The dyes can be excited with an argon ion laser at 488 nm, and detected in the FL1 channel (Oxidative Stress dye) and FL3 Channel (Hypoxia Red dye) on ost bench flow cytometers.
This kit is designed for fluorescence microscopy and/or flow cytometry using adherent or suspension cells.
Quality Control:
The testing is accomplished using flow cytometry method for assessment of hypoxic cells and/or cells with high levels of total oxidative stress in conjunction with dyes (provided in kit). Microscopy images are also obtained.
