Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin) Specificity / Sensitivity Phospho-Threonine-Proline Mouse Monoclonal Antibody (P-Thr-Pro-101) detects phospho-threonine only when followed by proline. This antibody reacts with proteins and peptides phosphorylated at the Thr-Pro motif in an otherwise highly context-independent fashion. This antibody is phospho-specific, but does not recognize phospho-threonine in the absence of an adjacent proline. This antibody does not react with phospho-tyrosine but does react with some phospho-serine peptides containing the phospho-serine-proline motif (e.g., phospho-Elk-1). Species Reactivity: All Species Expected Source / Purification Monoclonal antibody is produced by immunizing animals with synthetic phospho-threonine-proline-containing peptides. This antibody is a mouse IgM clone and can be recognized by anti-mouse Ig (whole molecule) secondary antibody. Background The MAPK and CDK families of serine/threonine protein kinases play important roles in cell signaling and cell cycle control. These kinases phosphorylate threonine or serine followed by a proline residue (1-6). To facilitate the study and discovery of new MAPK and CDK substrates, Cell Signaling Technology has developed antibodies that bind to phospho-threonine or phospho-serine followed by proline. As determined by ELISA using a wide variety of phospho-Thr-Pro peptides, Phospho-Threonine-Proline Monoclonal Antibody (P-Thr-Pro-101) recognizes the phospho-Thr-Pro motif in a highly context-independent fashion. It also interacts with a broad range of phospho-Thr-Pro-containing proteins as determined by western analysis of nocodazole-treated Jurkat cell extracts resolved on 2-D gels.
