Fig. 4From: Taxol-Induced Mitotic Block Triggers Rapid Onset of a p53-Independent Apoptotic Pathway Taxol induces the DNA nucleosomal ladders that are indicative of apoptosis DNA isolated from cells treated with 0 (Lane 1), 1 µM (Lane 2), or 100 nM taxol (Lane 3) for 6, 24, or 72 hr as indicated above the lanes. Arrowheads indicate positions of 1 kb ladder markers (Gibco-BRL). Panels underneath represent Ethidium bromide staining of the same gel prior to transfer.Back to article page
