A synthetic phospho-(Thr389) peptide corresponding to residues around (Thr389) of human p70 S6 kinase, coupled to KLH.

General description

p70 S6 kinase or p70S6K is a protein that belongs to Ser/Thr protein kinase family. It has a crucial role in cell growth and G1 cell cycle progression. It also has a pivotal role in phosphorylating eEF2k at a conserved serine residue and hence regulating the protein synthesis. Rabbit anti-phospho-(p70S6K) antibody can identify p70 S6 kinase and p85 S6 kinase when phosphorylated at (Thr389). Anti-phospho-S6-kinase (pThr389) antibody reacts specifically with p70 S6 kinase of rat, mouse and human. This product can also detect few phosphorylated isoforms of Protein Kinase C when present at high level in cells.

Physical form

Solution in 10 mM sodium HEPES, pH 7.5, containing 150 mM sodium chloride, 100 μg/ml bovine serum albumin and 50% glycerol


Anti-phospho-S6-kinase (pThr389) antibody can be used in western blotting (chemiluminescent) (diluted 1:1000) using serum-treated NIH3T3 cell extract or insulin-treated HeLa, COS, and C6 cell extracts.
