Induction of apoptosis by FWGE. A representative panel of human tumor cell lines was treated with an IC90 of FWGE for 48 h and floating cells were harvested by centrifugation for DNA extraction. DNA was seperated by DNA gel electrophoresis and stained with ethidium bromide subsequently. Typical DNA laddering indicative for apoptosis was visualized by UV light illumination.
