Product Description

The β-Catenin Antibody Sampler Kit provides an economical means of detecting total β-catenin as well as β-catenin phosphorlylated at various residues. The kit contains enough primary and secondary antibody to perform four Western blots with each antibody.


Specificity / Sensitivity

Each antibody in this kit recognizes only its specific target and does not cross-react with other family members.


Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser33, Ser37 and Thr41 of human β-catenin or residues surrounding Thr41 and Ser45 of human β-catenin. Polyclonal antibodies are purified by protein A and peptide affinity chromatography. Monoclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro714 of human β-catenin protein, a synthetic phosphopeptide corresponding to residues surrounding Ser552 of human β-catenin protein, or a synthetic phosphopeptide corresponding to residues surrounding Ser675 of human β-catenin.

β-Catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8).


Both Akt and PKA were shown to phosphorylate β-catenin at Ser552 and Ser675. Phosphorylation at Ser552 and Ser675 induces β-catenin accumulation in the nucleus and increases its transcriptional activity (9-12).
