Phospho-Skp2 (Ser64) Antibody recognizes endogenous levels of Skp2 protein only when phosphorylated at Ser64. This antibody also cross-reacts with an unidentified 160 kDa phosphoprotein in some cells.Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser64 of human Skp2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
