Subconfluent MDA-MB-231 TD, MDA-MB-436 TD, BT-549 TD cells were treated with either Vinorelbine, vehicle control, or Staurosporine. All cells, any suspended and attached, were harvested, lysed with a RIPA lysis buffer, and analyzed by immunoblot as previously described [24 (link)] with the following antibodies: Anti-Poly (ADP-ribose) polymerase (PARP; 1:1000, SCBT), Anti-acetyl-α-tubulin (Lys40) (D20G3) XP Rabbit mAb (1:1000; Cell Signaling), Anti-detyrosinated- α-tubulin Monoclonal (1:10,000: RevMAb) or Anti-detyrosinated-α-tubulin (1:1000; Abcam), Monoclonal Anti-α-tubulin Clone DM1A (1:2000; Sigma Aldrich) and β-actin (1:5000; AC-15, Sigma).
