β-catenin is part of a complex of proteins that constitute adherens junctions (AJs). AJs are necessary for the creation and maintenance of epithelial cell layers by regulating cell growth and adhesion between cells. The encoded protein also anchors the actin cytoskeleton and may be responsible for transmitting the contact inhibition signal that causes cells to stop dividing once the epithelial sheet is complete. β-catenin also plays a key role in Wnt signaling pathways and thus is involved in neural differentiation, synaptic plasticity, neurodegenerative disease, and prevention of apoptosis. Finally, this protein binds to the product of the adenomatous polyposis coli (APC) gene, which is mutated in the adenomatous polyposis of the colon. Mutations in this gene are a cause of colorectal cancer (CRC), pilomatrixoma (PTR), medulloblastoma (MDB), and ovarian cancer.

The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF™ solution contains no preservative; handle under aseptic conditions.

WB - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 1.0 - 10.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: immunfluorescence microscopy4 and immunohistochemical staining3.

For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 844603) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).

Antigen Details

88 kD armadillo repeat containing protein with an unstructured N and C terminal.

β-catenin localizes to cell-cell contacts (adherens junctions) and the cell membrane as well as the cytoplasmic pool of protein. β-catenin can also translocate to the nucleus and is in interphase found in puncta at the proximal end of centrioles. In mitosis, it localizes to the centrosomes at the spindle.

Wnt signaling pathway, regulation of cell-cell adhesion, neurogenesis, transcription, transcription regulation, early embryonic patterning, asymmetric cell division, stem cell renewal, and the epithelial to mesenchymal transition.
Wnt signaling pathway, apoptotic cleavage of cellular proteins, and EphB-EphrinB signaling.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
