p70 S6 Kinase 2 Antibody recognizes endogenous levels of total p70 S6 kinase 2 (S6K2) protein. This antibody does not cross-react with p70 S6 kinase 1 (S6K1) protein.Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro435 of human p70 S6 kinase 2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
