特異性：Binds peptides and proteins containing a motif composed of phospho-Ser with proline at the +2 position and arginine or lysine at the -3 position. Antibody binding is phospho-specific and largely independent of other surrounding amino acids. Weakly crossreacts with sequences containing phospho-Thr instead of phospho-Ser in this motif; with sequences containing phospho-Ser surrounded by Phe at the +1 position; with Arg/Lys at the -3 position. No crossreactivity is observed with corresponding non-phosphorylated sequences or with other phospho- Thr/Ser/Tyr -containing motifs.
純度：Affinity Purified Purified by Protein A and peptide affinity chromatography.
形状：Supplied as a liquid in 10mM sodium HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol.
