Reactive Oxygen Species (ROS)
Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.
ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

MitoSOX Red
0 ImagesCat. No.: HY-D1055CAS No.: 1003197-00-9MitoSOX Red is a live cell fluorescent probe that specifically targets mitochondria and is cell membrane permeable. MitoSOX Red enters mitochondria and is oxidized by superoxide but not by other ROS or RNS generating systems. The oxidized MitoSOX Red then binds to nucleic acids in mitochondria/nucleus, producing strong red fluorescence. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. In addition, superoxide dismutase (SOD) can prevent the oxidation of MitoSOX Red.
Excitation/emission wavelength: 510/580 nm.

Z-VAD-FMK
0 ImagesSynonyms: Z-VAD(OH)-FMKZ-VAD-FMK is a pan-caspase inhibitor and also an ICE-like protease inhibitor, which inhibits apoptosis by preventing the processing of CPP32 to its active form. Z-VAD-FMK sensitivity varies primarily due to differential expression of receptor-interacting protein 1 (RIP1). Z-VAD-FMK limits the cryopreservation-induced apoptosis by reducing caspase-3 activity of in vitro produced bovine embryos. Z-VAD-FMK is immunosuppressive in vitro and inhibits T cell proliferation without blocking the processing of caspase-8 and caspase-3. Z-VAD-FMK leads to a decrease in intracellular glutathione (GSH) with a concomitant increase in reactive oxygen species (ROS) levels in activated T cells. Z-VAD-FMK is due to oxidative stress via the depletion of GSH. Z-VAD-FMK can be used for the study of acute pancreatitis.
