    At circum-neutral p H, resorufin can be detected by visual observation of its pink color or by fluorimetry, with an excitation maximum at 530-570 nm and an emission maximum at 580-590 nm of this same solution is increased, dihydroresorufin is oxidized back to resorufin, and this reversible reaction can be used to monitor if the redox potential of a culture medium remains at a sufficiently low level for anaerobic organisms. This means that it has a large change in perceived color hue when the thickness or concentration of observed sample increases or decreases.

    Cell Viability Resazurin Assay ab129732 Mitochondrial viability stain in long term toxicity. HepG2 cells previously cultured in glucose or galactose substrate media were seeded at 10,000 cells per well and allowed to adhere overnight. Metabolic Proliferation Assays. Assays that measure metabolic activity are suitable for analyzing proliferation, viability, and cytotoxicity. The reduction of tetrazolium salts such as MTT, XTT, WST-1 to colored formazan compounds or the bioreduction of resazurin only occurs in metabolically active cells. To examine whether the growth inhibition by chloroquine was a consequence of affected cell viability, we analyzed the percentage of nonviable cells in untreated or chloroquine-treated cultures using a trypan blue exclusion assay. The results summarized in Fig. 1B show that chloroquine affects glioma cell viability in a dose-dependent manner.

    Resazurin is reduced to resorufin by aerobic respiration of metabolically active cells, and it can be used as an indicator of cell viability. Usually, resazurin is available commercially as the sodium salt.

  6. The resazurin assay also known as Alamar Blue assay offers a simple, rapid, and sensitive measurement for the viability of mammalian cells and bacteria. Living cells are metabolically active and are able to reduce via mitochondrial reductase, the nonfluorescent dye resazurin to the strongly-fluorescent dye resorufin Fig. 10.5.

    Cell viability applications. Resazurin is reduced to resorufin by aerobic respiration of metabolically active cells, and it can be used as an indicator of cell viability. It was first used to quantify bacterial content in milk by Pesch and Simmert in 1929. It can be used to detect the presence of viable cells in mammalian cell cultures. AlamarBlue HS Cell Viability Reagent is a ready-to-use resazurin-based solution that functions as a cell health indicator by using the reducing power of living cells to quantitatively measure viability. Upon entering living cells, resazurin is reduced to resorufin, a compound that is red in color and highly fluorescent. Resazurin is commonly used to measure bacterial and eukaryotic cell viability through its reduction to the fluorescent product resorufin. When tested on various bacterial taxa at the recommended concentration of 44 μM, a potent bactericidal effect was observed against various Francisella and Neisseria species, including the human pathogens.

    A Long-Term Study of Hydroxychloroquine Withdrawal on. We evaluated the long-term effectiveness of maintaining treatment with hydroxychloroquine sulphate HCQ to prevent major flares in quiescent SLE. Forty-seven patients with quiescent SLE who had been randomized to take HCQ n = 25 or placebo n = 22 as part of a 24-week withdrawal trial were evaluated for an additional 3 years.
