Cytotoxicity positive control

WebProtocols used to measure cytotoxicity in vitro differ widely (Figure 2). Often assay plates are set up containing cells and allowed to equilibrate for a predetermined period before adding test compounds. Alternatively, cells may be added directly to plates that already contain library compounds. WebThe positive control induced a high degree of toxicity in all in vitro tests performed, indicating that the toxicity observed in the direct contact assay was due to in situ extraction of toxic components. In the direct contact assay the negative control tested on the mouse fibroblasts resulted in a significant reduction of cell survival.
