Applications Dilution Species-Reactivity Sensitivity MW (kDa) Isotype
W 1:1000 Human,All Species Expected, Endogenous Rabbit IgG

Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-Ser-Pro-Pro Motif [pSPP] Rabbit mAb recognizes endogenous levels of proteins only when phosphorylated at serine within the context of the SPP motif. This antibody does not cross-react with proteins phosphorylated at threonine, or with serine residues phosphorylated in other contexts.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide library containing the phospho-Ser-Pro-Pro motif.

Western Blotting

Western Blotting

Western blot analysis of extracts from HCT 116 cells, G0 cells that were serum starved and contact inhibited (36 hr) or mitotic cells treated with thymidine (2 mM, 18 hr) followed by Nocodazole #2190 (50 ng/ml, 20 hr), using Phospho-Ser-Pro-Pro Motif [pSPP] Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower).


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.

The S/TPP motif matches the consensus sequence for targeted phosphorylation by Cdc2 (7,8), ERK1, ERK2 (9), SAPK/JNK, CDK5, and GSK3 (10).
