WebCell cytotoxicity and proliferation assays are generally used for drug screening to detect whether the test molecules have effects on cell proliferation or display direct cytotoxic effects. Regardless of the type of cell-based assay being used, it is important to know how many viable cells are remaining at the end of the experiment. Webnumber of dead cells (cytotoxicity assay), the number of live cells (viability assay), the total number of cells, or the mechanism of cell death (e.g., apoptosis). Table 1 shows a comparison of Promega’s homogeneous cell-based assays and lists the measured parameters, sensitivity of detection, incubation time, and detection method.

Webcytotoxicity [ si″to-tok-sis´ĭ-te] 1. the degree to which an agent has specific destructive action on certain cells. 2. the possession of such destructive action, particularly in reference to lysis of cells by immune phenomena and to antineoplastic agents that selectively kill dividing cells. adj., adj cytotox´ic. Cytotoxicity is the quality of being toxic to cells. Examples of toxic agents are an immune cell or some types of venom, e.g. from the puff adder (Bitis arietans) or brown recluse spider (Loxosceles reclusa). See more Treating cells with the cytotoxic compound can result in a variety of cell fates. The cells may undergo necrosis, in which they lose membrane integrity and die rapidly as a result of cell lysis. The cells can stop actively growing … See more Some chemotherapies contain cytotoxic drugs, whose purpose is interfering with the cell division. These drugs cannot distinguish between … See more Antibody-dependent cell-mediated cytotoxicity (ADCC) describes the cell-killing ability of certain lymphocytes, which requires the target cell being marked by an antibody.

Cytotoxicity definition of cytotoxicity by Medical dictionary
WebAntibody-dependent cellular cytotoxicity (ADCC) is a cytolytic process that is dependent on the cooperative interaction of several different cellular and humoral constituents of the … WebDead-cell Protease Release Cytotoxicity Assay. When cells die and lose membrane integrity, dead-cell proteases are released. A luminogenic substrate (CytoTox-Glo™ Cytotoxicity Assay, Cat.# G9290) or fluorogenic substrate (CytoTox-Fluor™ Cytotoxicity Assay, Cat.# G9260) can then be used to measure dead-cell protease activity (Figure 4). Antibody-dependent cellular cytotoxicity (ADCC), also referred to as antibody-dependent cell-mediated cytotoxicity, is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies. It is one of the mechanisms through which antibodies, as part of the humoral immu… port washington ballot
