Threonine-Proline (Thr-Pro), phosphorylated

May be stored at 4 °C for short-term only. For long-term storage, store at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Recognizes Mouse phospho- threonine only when followed by proline. It reacts with proteins/peptides phosphorylated on the Thr-Pro motif in an otherwise highly context-independent fashion. The phosphospecific antibody does not recognize phospho-threonine in the absence of an adjacent proline. 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).<br>Cross Reactivity: All Species
