Cytotoxicity positive control
WebFeb 23, 2011 · Recent studies demonstrate that classic cytotoxicity assays may not be suitable to assess NM toxicity since NMs can interfere with assay reagents or detection systems thereby generating false positive/negative results [9–11]. Due to the lack of standards for NM testing, current data on NM toxicity are often inconsistent and can … WebLike every cell experiment, cytotoxicity assays require appropriate controls [8]. Besides the negative control (untreated cells) and positive control (maximum cytotoxicity signal: …

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.
