ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 3J7 is a ZooMAb rabbit recombinant monoclonal antibody that detects beta-catenin. It targets an epitope with in the N-terminal region of isoform 1.

Immunogen

GST/His-tagged recombinant fragment corresponding to the first 100 amino acids from the N-terminal region of human beta-catenin.

Application

Anti-beta Catenin, clone 3J7 ZooMAb, Cat. No. ZRB05665, is a recombinant Rabbit Monoclonal Antibody that detects beta-catenin and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected beta-Catenin in NIH/3T3 cell lysate.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected beta-Catenin in HUVEC and A431 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected beta- Catenin in human pancreas tissue sections.

Target description

Catenin beta-1 (UniProt: P35222; also known as beta-catenin) is encoded by the CTNNB1 (also known as CTNNB, OK/SW-cl.35, PRO2286) gene (Gene ID: 1499) in human. Catenin beta-1 is a key downstream component of the canonical Wnt signaling pathway that participates in intercellular adhesion and Wnt-mediated transcriptional activation. In the absence of Wnt, it forms a complex with AXIN1, AXIN2, APC, CSNK1A1, and GSK-3 beta that promotes phosphorylation on N-terminal serine and threonine residues that leads to its subsequent degradation by the proteasome. In the presence of Wnt ligand, it is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, which leads to activation of Wnt responsive genes. O-glycosylation at serine 23 is reported to decrease its nuclear localization and transcriptional activity. Wnt/beta-catenin signaling is shown to be essential for embryonic stem cell (ESC) pluripotency and differentiation. In ESC beta-catenin is trimethylated on Lysine 49 by Ezh2 methyltransferase and this trimethylated form represses neuronal differentiation genes Sox1 and Sox3. Mutations in CTNNB1 gene are shown to cause colorectal cancers, medulloblastoma, and ovarian cancers. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
