FIG. 4.
Arachidonic acid induced apoptosis in Vector cells but not in BM3 cells. Quiescent BM3 cells and Vector cells were treated with or without arachidonic acid (10 μM) for 48 h in the absence of other apoptosis-inducing stimuli and then subjected to assessment of DNA laddering. Leftmost lane, 100-bp DNA ladder; rightmost lane, lambda DNA-HindIII size marker.
