  1. General Cytotoxicity Assessment by Means of the MTT Assay

  2. People also ask
    The MTT method is a frequently used cytotoxicity assay. When cells die, they lose the ability to convert MTT into formazan, thus color formation serves as a useful and convenient marker of viable cells.
    An MTT assay is a colorimetric assay based on assessing the cell metabolic activity. A549 Lung adenocarcinoma cell line was used to see the cytotoxic potential of a new drug for initial screening of apoptosis or necrosis.
    It is more commonly the latter, but interpre-tation of the assay is often assumed to be a measure of viability. The MTT assay should not be interpreted or reported as a cell viability assay, unless validation and calibration have been conducted. The assay works by adding a yellow-colored compound (the MTT reagent) to a cell culture.
    So, the zest of the assay types is explained above and since the detailed pro-tocols for all these categories will be very vast, therefore, in this chapter we discuss the selective and the most commonly used assays such as the Trypan blue exclusion method, MTT assay, XTT assay, LDH assay and SRB assay for cell cytotoxicity analysis.
