Anti-Active-β-Catenin (Anti-ABC) Antibody, clone 8E7

Description

• General description: Catenins are proteins found in complexes with cadherin cell adhesion molecules of animal cells. The first two catenins that were identified became known as α-catenin and β-catenin. α-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. When β-catenin was sequenced it was found to be a member of the armadillo family of proteins. These proteins have multiple copies of the so-called armadillo repeat domain which is specialized for protein-protein binding. An increase in β-catenin production has been noted in those people who have Basal Cell Carcinoma and leads to the increase in proliferation of related tumors. When β-catenin is not associated with cadherins and α-catenin, it can interact with other proteins such as Catenin Beta Interacting Protein 1 (ICAT) and adenomatosis polyposis coli (APC). Recent evidence suggests that β-catenin plays an important role in various aspects of liver biology including liver development (both embryonic and postnatal), liver regeneration following partial hepatectomy. HGF-induced hepatpomegaly, liver zonation, and pathogenesis of liver cancer.
• Specificity: Recognizes active form of β-catenin, dephosphorylated on Ser37 or Thr41.
• Immunogen: Epitope: The epitope corresponds to amino acid residues 36-44 (HSGATTTAP) of human β-catenin.
• Application: Immunocytochemistry: This antibody was used in immunocytochemistry and showed positive staining on the membrane and cytosol.This antibody has also been reported by an independent laboratory to show positive immunostaining for beta-catenin in LiCl-treated 293T cells fixed with methanol (Staal, Frank J. T., 2002).Flow Cytometry: This antibody was used in flow cytometry at an optimal 1 μg/mL concentration.Immunohistochemistry: This antibody was used in immunohistochemistry on a colorectal carcinoma tissue array at a 1:300 dilution.This antibody has also been reported by an independent laboratory to detect beta-catenin in mouse embryo sections (Van Noort, M., 2002).
• Quality: Routinely evaluated by immunoblot on RIPA lysates from A431 cells.Western Blot Analysis: 0.2-2 µg/mL of this antibody detected β-catenin in RIPA lysates from A431 cells.
