Resumo

The main goal of this study was to develop a straightforward and rapid microplate assay for measuring propidium iodide (PI) in C2C12 cells. The PI method has proven to be an efficient quantitative assay for analyzing cell viability through PI fluorescence analysis. Importantly, the protocol takes less than 30 min and the results are reproducible. C2C12 cells were exposed to an increasing concentration of palmitate for a period of 24 h to induce cell death, and the PI fluorescence increased in a concentration-dependent manner. Evaluation of mitochondrial function and the production of reactive oxygen species confirmed the deleterious effects of palmitate. Also, the microplate PI assay demonstrated high sensitivity, as indicated by the detection of modest fluctuations in cell viability in response to catalase overexpression in palmitate-treated cells. The microplate PI assay, therefore, offers an accurate method for use in in-vitro studies. (AU)
