synthetic phosphopeptide corresponding to the region that contains serines 33 and 37 of human β-catenin.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


The antibody is inhibited more efficiently by the pSer37 peptide than by the pSer33 peptide and is not inhibited by the nonphos­phorylated peptide. It does not detect the unphos­phorylated or the Ser33 phosphorylated protein and does not recognize phosphorylated plakoglobin.


Monoclonal Anti-phospho-ß-Catenin (pSer33/pSer37) antibody is suitable for
• indirect ELISA
• microarray
• western blot at a dilution of 5-10μg/mL using whole cell extract of cultured human 293 cells treated with proteasome inhibitor MG132
