Three human tumor cell lines of widely differing radiosensitivity were used to examine the characteristics of the 3-[4,5-dimethyl(thiazol-2-yl)-3,5-diphery]tetradium bromide (MTT) assay and to select suitable conditions for its use in assessing the response of cells to ionizing radiation. The optimal concentration of MTT and the time of incubation of the cells with MTT were individualized for e...
Introduction: The tetrazolium salt 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) used extensively to measure the quantitative survival and proliferation of mammalian cells. analysis is based upon reduction MTT by metabolically active cells insoluble formazan crystals. Flavonoids are a large group natural compounds found in plants with variable phenolic structures. Flavono...
Background: Susceptibility test is a useful tool for selecting and modifying appropriate treatment for tuberculosis. Objective: To evaluate a direct colorimetric assay based on 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide (MTT) for a rapid detection of rifampicin resistance. Methods: Sputum was inoculated directly into 7H9 broth supplemented with PANTA (antibiotic mixture) and o...
