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.Product Details

ICFC - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
- Excitation Laser
Red Laser (633 nm)
- 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).

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.
