<p class="jove_content"> Il test MTT è considerato un metodo versatile e di conseguenza la vitalità delle cellule potrebbe essere valutato su vari trattamenti. La produzione di formazan risultante sembra essere proporzionale al livello del metabolismo energetico nelle cellule. Pertanto, è possibile misurare le cellule metabolicamente attiva anche in assenza della proliferazione cellulare. La quantità di formazan prodotta è proporzionale alla quantità di MTT nel mezzo di incubazione. Mentre, la concentrazione di MTT che è necessario per o...

cellular toxicity of nanogenomedicine in mcf-7 cell line: mtt assay

<p class="jove_content">Citotossicità della nanogenomedicine futuristico (per esempio, a breve RNA interferente e antisenso) può ostacolare il suo sviluppo clinico. Di questi, il gene-based medicine e / oi suoi vettore può provocare la tossicità cellulare. Per la valutazione della citotossicità tale, una metodologia comune dipende in gran parte l&#39;utilizzo del 3 - (4, 5-dimetil-2-tiazolil) -2, 5-difenil-2H-tetrazolio bromuro (MTT) che è stato ampiamente utilizzato come un approccio colorimetrico basato su l&#39;attività degli enzimi deidrogenasi mitocondriale nelle cellule. In questa inchiesta, cellule MCF-7 sono stati inoculati in piastra a 96 pozzetti e al 50% confluenza sono stati trattati con nanopolyplexes diversi e sottoposti a test MTT dopo 24 ore. MTT solubile in acqua gialla viene metabolizzato dalle cellule metabolicamente attivo alla insolubile in acqua viola formazan, che viene ulteriormente disciolto in tampone pH dimetilsolfossido e Sornson s 10.5. Il prodotto risultante può essere quantificata con spettrofotometria utilizzando un lettore di piastre a 570 nm.</p>
