  • Product nameAnti-Phosphothreonine-Proline / Phosphoserine-Proline antibody
    See all Phosphothreonine-Proline / Phosphoserine-Proline primary antibodies
  • Description
    Rabbit polyclonal to Phosphothreonine-Proline / Phosphoserine-Proline
  • SpecificityThis antibody specifically reacts to proteins containing phosphothreonine-proline motifs, it also reacts to the phosphoserine-proline motif to a similar degree (pT-P and pS-P motif). The antibody does not react to phosphothreonine, phosphoserine or phosphotyrosine. The antibody will selectively recognize the phosphothreonine-proline motif of MBP, which is the site of phosphorylation by ERK1/ERK2.
