  1. Does chloroquine increase cell viability resazurin


    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.

    Count cells and evaluate cell viability by trypan blue exclusion or equivalent test. Do not start the assay if cell viability is less than 90%. Dilute to 1 x 10 6 cells per ml in cell culture medium. B. 3-D Spheroid Fluorometric Proliferation/Viability Assay. Assay Preparation – Prior to Day 0. Establish assay parameters and appropriate controls. Chloroquine does not treat the hypnozoite liver stage forms of Plasmodium and will therefore not prevent relapses of malaria due to P. vivax or P. ovale. Additional treatment with an anti-malarial agent active against these forms, such as an 8-aminoquinoline, is required for the treatment of infections with P. vivax and P. ovale. Use of Resazurin as an Indicator in both Cytotoxicity and Cell Viability Assays Resazurin reduction is a common reporter for both cytotoxicity and cell viability assays. Using the reaction conditions recommended for the CytoTox-ONE™ Assay i.e. reduced temperature and short incubation time, only a negligible amount of resazurin is reduced.

    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.

    Nov 29, 2016 Chloroquine did not impact cell viability at concentrations of 50 μM or lower Figure 1 E. We further analyzed whether chloroquine treatment could protect Vero cells from ZIKV infection as assessed by cell viability. Chloroquine, ranging from 12.5 to 50 μM, increased cell viability from 55% up to 100% Figure 1 F. Cell viability assays A stock solution of 1 mg/mL 3.981mM resazurin was pre-pared in 100% DMso. For each experiment, fresh dilutions of 0.1 mg/mL resazurin were prepared in tris-hcl 5 mM ph 5.5. cells were incubated with resazurin at a concentration of between 1 µM and 500 µM, for 10 min to 3 h. resofurin fluo- Effects of CQ on cell viability and glutamate‐induced cell death in HT22 cells. a CQ is not toxic up to 10 μM. HT22 cells were cultured in 96‐well plates with various concentrations of CQ for 24 or 48 h. Cell viability was determined by WST‐1 assay, as described in Materials and methods section.

    Volume of distribution - Wikipedia If the drug distributes into all body water the volume of distribution would increase to approximately = 0.57 l/kg If the drug readily diffuses into the body fat the volume of distribution may increase dramatically, an example is chloroquine which has a = 250-302 l/kg
