    Chloroquine resazurin assay results


    Current treatment options are, at best, palliative. The objectives of this study were to evaluate a panel of nineteen candidate compounds for antiviral activity against FCo V to determine viable candidates for therapy.

    For resazurin microplate assay REMA and hypoxic resazurin reduction assay HyRRA, the bacterial stock was subcultured in 7H9-S or Dubos-S medium supplemented with 0.05% glycerol and 0.05% Tween 80 under aerobic conditions with shaking at 190 rpm to logarithmic phase OD 595 ∼0.5. Resazurin 7-Hydroxy-3 H -phenoxazin-3-one 10-oxide is a blue dye, itself weakly fluorescent until it is irreversibly reduced to the pink colored and highly red fluorescent resorufin. It is used as an oxidation-reduction indicator in cell viability assays for both aerobic and anaerobic respiration. The resazurin dye can be measured in fluorescence or absorbance mode. However fluorescence mode measurement offers greater assay linearity, reproducibility, robustness and sensitivity. Resazurin assay protocol summary - add resazurin reagent to cells in growth media and incubate for 4 hr at 37ºC - analyze with microplate reader

    Plaque reduction and virus yield reduction assays were performed to confirm antiviral effects of candidate compounds identified during screening, and the possible antiviral mechanisms of action of these compounds were investigated using virucidal suspension assays and CPE inhibition and IFA-based time of addition assays. A resazurin-based cytopathic effect inhibition assay, which detects viable cells through their reduction of the substrate resazurin to fluorescent resorufin, was developed for screening compounds for antiviral efficacy against FCo V.

    Resazurin Cell Viability Assay offers a simple, rapid, reliable, sensitive, safe and cost-effective measurement of cell viability. This kit performs at least as well as other commercial resazurin-based cell proliferation assay kits such as alamarBlue® or CellTiter-Blue®. A simple method to measure cell viability in proliferation and cytotoxicity assays Abstract Resazurin dye has been broadly used as indicator of cell vi-ability in several types of assays for evaluation of the biocompatibility of medical and dental materials. Mitochondrial enzymes, as carriers of Store at –20°C Resazurin Cell Viability Kit Description The Resazurin Cell Viability Kit is a fluorescent assay that detects cellular metabolic activity. The blue nonfluorescent resazurin reagent is reduced to highly fluorescent resorufin by dehydrogenase enzymes in metabolically active cells. This conversion only occurs in
