Figure 4From: Metabolism modifications and apoptosis induction after Cellfood™ administration to leukemia cell linesDNA fragmentation of leukemia cells after 72 h of incubation with CF (5 μl/ml). Apoptotic DNA fragmentation was qualitatively analyzed by agarose gel electrophoresis. Lane 1: 1 kb DNA ladder marker; lane 2: negative control (untreated cells); lane 3: CF treated cells; lane 4: positive control (etoposide).Back to article page
