Figure 6: Aoptotic DNA fragmentation in HeLa cells by F. solani organic extract. Untreated “C” HeLa cells or those treated with indicated concentrations (in units of μg/mL) of F. solani organic extract for 24 h were harvested for DNA extraction as described in “Materials and Methods”. Extracted DNAs were analyzed by electrophoresis on 0.8% agarose gel. The gel was stained with ethidium bromide and viewed under a UV transilluminator. Fragmented internucleosomal DNA appears as ladder. “M” represents 100 bp DNA marker with a sharp band at 500 bp.
