Mycobacterium tuberculosis high content assay

mtb1We will measure the intracellular activity of small molecule compounds against murine macrophage-like cells (RAW264.7) infected with M. tuberculosis. The full procedure is detailed in the publications listed below. Briefly, RAW cells are infected with M. tuberculosis constitutively expressing DsRed. We expose the infected cells to test compounds for 72 hours. After exposure, RAW cell nuclei are stained; cells and bacteria are imaged and counted. Anti-tubercular and cytotoxic activity is measured and reported as IC50 (concentration required to inhibit growth by 50%).
