FIG 9.

Rb knockdown cells accumulate lower levels of late proteins. (A) Serum-starved Scr or Rb2 cells were mock infected or infected with AD169 at an MOI of 1, and equal amounts of protein lysates harvested at the indicated hours postinfection were analyzed by Western blotting. (B) The data are mean values of pp150 protein relative to tubulin and normalized to Scr ± standard deviations from five biological replicates. Statistical significance was determined by Student's t test prior to normalization (**, P < 0.01).
