• Product name
    Anti-alpha 2 Catenin antibody
    See all alpha 2 Catenin primary antibodies
  • Description
    Rabbit polyclonal to alpha 2 Catenin
  • Specificity
    Anti-alpha-N-Catenin recognizes alpha-N-catenin (102 kDa) by immunoblotting. Staining of the alpha-N-catenin band in immunoblotting is specifically inhibited with the alpha-N-catenin immunizing peptide (human, amino acids 171-186).
  • Tested applications
    Suitable for: IHC-Fr, WBmore details
  • Species reactivity
    Reacts with: Mouse, Human
    Predicted to work with: Chicken
  • Immunogen

    Synthetic peptide:


    conjugated to KLH, corresponding to amino acids 171-186 of Human alpha 2 Catenin.

  • General notes
    Storage in frost-free freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.



Our Abpromise guarantee covers the use of ab11347 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
  • Application notes
    IHC-Fr: 1/500.

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      May function as a linker between cadherin adhesion receptors and the cytoskeleton to regulate cell-cell adhesion and differentiation in the nervous system. Regulates morphological plasticity of synapses and cerebellar and hippocampal lamination during development. Functions in the control of startle modulation.
    • Sequence similarities
      Belongs to the vinculin/alpha-catenin family.
    • Cellular localization
      Cytoplasm. Cytoplasm > cytoskeleton. Cell junction > adherens junction. Cell membrane. Cell projection > axon. Recruited to the nucleus upon ZNF639 overexpression.

    • ab11347 staining alpha 2 Catenin (left) in Mouse cortical ventricular zone tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with 4% paraformaldehyde in PBS overnight at 4°C, then saturated in 30% sucrose at 4°C (for at least 18 hours). Fixed and saturated brains were embedded in OCT compound and frozen rapidly with dry ice, and then 12µm cyrosections collected and stored at -80°C. Samples were incubated with primary antibody (1/500). Middle - non-phosphorylated active beta catenin, Right - merge. Beta catenin co-localizes with alpha catenin at the apical junctions rings.
