Specificity / Sensitivity

Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb recognizes endogenous β-catenin protein when residues Ser33, Ser37, and Thr41 are not phosphorylated. It does not detect β-catenin protein if tri-phosphorylated at Ser33/Ser37/Thr41.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser37 of human β-catenin protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from 293T cells, untreated (-) or treated (+) with LiCl (20 mM, 20 hr at 37ºC), using Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb (left) and β-Catenin Antibody #9562 (right). Equal protein loading was confirmed using β-Tubulin (9F3) Rabbit mAb #2128.

ELISA-Peptide

ELISA-Peptide

Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb specificity was determined by peptide competition ELISA. Graph depicts binding of the antibody to non-phospho-β-catenin (Ser33/37/Thr41) peptide in the presence of increasing concentrations of competitor peptides. As shown, non-phospho-β-catenin peptides compete for binding, whereas tri-phospho-β-catenin (Ser33/37/Thr41) peptide does not compete for binding.

Western Blotting

Western Blotting

Western blot analysis of extracts from 293T cells, untreated (-) or treated (+) with MG132 (10 μM, 4 hr at 37ºC), using Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb (left), Phospho-β-Catenin (Ser33/37/Thr41) Antibody #9561 (center), or β-Catenin (6B3) Rabbit mAb #9582 (right). Note that Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb fails to detect poly-ubiquitinated β-catenin in MG132-treated cells, indicating its specificity for stabilized protein.

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HCT 116 cells and either 5 μl of Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human Axin2 Intron 1 Primers #8973, SimpleChIP® Human CaMK2D Intron 3 Primers #5111, human c-Myc promoter primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin embedded cell pellets, HeLa (left) or NCI-H28 (right), using Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb.

Note the absence of staining only in the presence of the non-phospho-β-catenin (Ser33/37/Thr41) peptide, demonstrating non-phospho specificity.

IHC-P (paraffin)

IHC-P (paraffin)

Immunohistochemical analysis of paraffin-embedded Apc (Min/+) mouse intestinal adenoma (left) and adjacent normal intestinal epithelium (right) using Non-phospho (Active) beta-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb. Note the nuclear accumulation of active beta-Catenin in the adenoma cells.

Background

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-3 (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).

Non-phospho (Active) β-Catenin (Ser33/37/Thr41) (D13A1) Rabbit mAb is designed to specifically recognize the stabilized form of β-catenin, i.e., protein that has not been phosphorylated by GSK-3, and thus is functionally active in cell-cell adhesion and/or the canonical Wnt signaling pathway.
