Western blot analysis of lysates from unsynchronized (U) and nocodazole (N) treated (50ng/ml for 48 hours) HT29 cells using Phospho-p70 S6 Kinase (Ser371) Antibody (B) and p70 S6 Kinase Antibody #9202 (D). Incubation of the nitrocellulose membrane with calf intestinal alkaline phosphatase (CIP) after Western transfer abolishes the phospho-p70 S6 Kinase signal (A), but has no effect on the total p70 S6 kinase signal (C).

Western blot analysis of lysates from 293 cells grown in low serum, then treated with 20% serum for 30 minutes alone or after 1 hour preincubation with rapamycin (10nM) #9904 or LY294002 (50uM) #9901, using Phospho-p70 S6 Kinase (Ser371) Antibody (upper) or p70 S6 Kinase Antibody #9202 (lower).
