Redox assay
WebCatalog number: X6493. XTT is used to assess cell viability as a function of redox potential. Actively respiring cells convert the water-soluble XTT to a water-soluble, orange colored formazan product. Unlike MTT, XTT does not require solubilization prior to quantitation, thereby reducing the assay time in many viability assay protocols. WebAntioxidant enzymes and other redox molecules counteract the ROS that cause oxidative damage. There are three classes of antioxidants used as oxidative stress markers: small molecules, enzymes, and proteins (such as albumin).

WebRedox reactions are affected by pH and are therefore frequently assayed in buffered systems to mimic physiological conditions. However, the type of buffer used in redox … WebAn oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction.
