(A) Immunoblot of total cell proteins of WT, βDDDE440 (+ α-COOH terminus-β chimera) and βDDDD440 (+ α-COOH terminus β) chimera mutants probed with the polyclonal anti-polyG antibodies (top), monoclonal anti–β-tubulin antibodies, DM1B (middle), and monoclonal anti–α-tubulin antibodies, DM1A (bottom). Approximately equal amounts of total cell proteins were loaded in each lane. (B) A Western blot of ciliary proteins of the βDDDDGD442 (+ α-COOH terminus-β chimera) and βDDDE440 (+ α-COOH terminus-β chimera) mutants probed with several antitubulin antibodies. Equal amounts of total proteins were loaded into each lane. The same blot was probed sequentially using the ECL system. After each exposure, the antibodies were removed, and the blot was reprobed according to manufacturer's instructions. The following antibodies were used: anti–β-tubulin, DM1B; anti–α-tubulin, DM1A; antimonoglycylated tubulin, TAP 952; and antipolyglycylated tubulin, AXO 49.
