Western blot analysis of extracts from HeLa cells, asynchronous or synchronized in mitosis, using Phospho-PLK1 (Thr210) (D5H7) Rabbit mAb (upper) or total PLK1 (208G4) Rabbit mAb #4513 (lower). Mitotic synchronization was performed by thymidine block followed by release into nocodazole and mitotic shake-off.
Western blot analysis of extracts from HeLa cells, asynchronous or synchronized in mitosis, using Phospho-PLK1 (Thr210) (D5H7) Rabbit mAb. The antibody was pre-incubated with a PLK1 phospho-Thr210 peptide or nonphospho-peptide as indicated. Mitotic synchronization was performed by thymidine block followed by release into nocodazole and mitotic shake-off.
