Heat-mediated antigen retrieval is recommended prior to staining, using a 10mM citrate buffer, pH 6.0, for 10 minutes followed by cooling at room temperature for 20 min. Following antigen retrieval, incubate samples with primary antibody for 30 min at room temperature. A suggested positive control is breast carcinoma.
40S ribosomal protein S6 (also known as RPS6) is a ~31 kDa substrate of p70 S6 kinase (p70S6K) and a major component of translational machinery involved in protein synthesis, cell growth, proliferation, and metabolism. RPS6 undergoes phosphorylation on multiple serines in the carboxyl terminal region in the order 236-->235-->240-->244-->247, due to the positions of these amino acid residues on the alpha-helix. Hyperphosphorylation of RPS6 stimulates protein synthesis that mediates progression through the cell cycle.
