Data Examples
Detection of Human Phospho-p70 S6 Kinase by Western Blot. Western blot shows lysates of MCF‑7 human breast cancer cell line untreated (-) or treated (+) with 100 ng/mL Recombinant Human IGF‑I (Catalog # 291-G1) for 1 hour. PVDF membrane was probed with 1:1000 dilution of Rabbit Anti-Human/Mouse/Rat Phospho-p70 S6 Kinase (T421/S424) Monoclonal Antibody (Catalog # MAB8965) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). Specific bands were detected for Phopsho-p70 S6 Kinase (T421/S424) at approximately 70 kDa and Phospho-p85 S6 Kinase (T444/S447) at 85 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: p70 S6 Kinase
p70 S6 Kinase (p70S6K) is responsible for the phosphorylation of 40S ribosomal protein S6 and is ubiquitously expressed in human adult tissues (1). p70S6K is activated by serum stimulation and this activation is inhibited by wortmannin and rapamycin. p70S6K activity undergoes changes in the cell cycle and increases 20-fold in G1 cells released from G0 (2). p70S6K activation requires sequential phosphorylations at proline-directed residues in the putative autoinhibitory pseudosubstrate domain, as well as T389, a site phosphorylated by Phosphoinositide-Dependent Kinase 1 (PDK1).
