Immunofluorescent analysis of alpha Catenin using Catenin alpha Monoclonal Antibody (1G5) (Product# MA1-2000 ) shows staining in A2058 Cells. Catenin alpha (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control) or with an antibody recognizing Catenin alpha (Product# MA1-2000 ) at a dilution of 1:20 over night at 4 °C, washed with PBS and incubated with a DyLight-488 conjugated secondary antibody (Product# 35552 for GAR, Product# 35503 for GAM). Images were taken at 60X magnification.

MA1-2000 detects alpha catenin from human samples.
MA1-2000 has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~102 kDa protein representing alpha catenin from scc-1 cell extract. In Western blot, this antibody did not cross-react with mouse samples. MA1-2000 can also be used in immunoprecipitation and immunofluorescence procedures.
The MA1-2000 immunogen is a 90 kDa MBP/alpha catenin fusion protein purified via an amylose column.
Alpha catenin is a member of the b-catenin family of cytosolic proteins. Alpha catenin interacts with N-cadherin and b-catenin on the cytosolic side of adherins junctions to mediate the interaction with the actin cytoskeleton. Alpha catenin is a homodimer in solution, but dissociates to form a 1:1 heterodimer with b-catenin in order to interact with cadherins. Mice that have a-catenin ablated in their surface epithelium demonstrate reduced hair growth, multinucleated cells, extensive proliferation and a general cancerous phenotype.
