Human Lung Carcinoma Cells (A-549 Line)

A human lung carcinoma (A-549) cell culture was immunofluorescently labeled with primary anti-cytokeratin (an intermediate filament protein) mouse monoclonal antibodies followed by goat anti-mouse Fab fragments conjugated to Marina Blue. The culture was also stained with MitoTracker Red CMXRos and SYTOX Green to probe the mitochondrial network and nuclei, respectively.
