General description

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.

Anti-Catenin- a2, clone 3F7 ZooMAb, Cat. No. ZRB1108, is a recombinant Rabbit monoclonal antibody that targets Catenin-a2 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Catenin-a2 (UniProt: P26232; also known as Alpha N-catenin, Alpha-catenin-related protein) is encoded by the CTNNA2 (also known as CAPR) gene (Gene ID: 1496) in Human. Catenins are a large family of cell-cell adhesion molecules that are involved in development and in epithelial cell polarity. They are reported to associate with both E- and N-cadherins. The association of catenins to cadherins creates a complex that is linked to the actin filament network, and which seems to be of primary importance for cadherins cell-adhesion properties. Catenin- a2 is a peripheral membrane protein that is expressed in neural tissues. It is expressed in the developing cortical plate and marginal zone of 20-week-old human fetal brain. It functions as a linker between cadherin adhesion receptors and the cytoskeleton to regulate cell-cell adhesion and differentiation in the nervous system and is required for proper regulation of cortical neuronal migration and neurite growth. It is also reported to act as negative regulator of Arp2/3 complex activity and Arp2/3-mediated actin polymerization and hence suppresses excessive actin branching which would impair neurite growth and stability. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
