Catenin-b plays a central role in cell adhesion, bridging between cadherins and actin cytoskeleton. These activities are regulated through its differential interaction with several molecular partners, including cell-cell adherens junction (AJ) molecules, components of its degradation complex, and transcription factors (1, 2, 3). Beta-Catenin is composed of three domains: a central armadillo repeat domain and two N- and C-terminal tails. Beta-catenin can be phosphorylated by serine-threonine kinase, such as GSK-3 (4). The phosphorylated beta-catenin affects the protein association of beta-catenin to E-cadherin and alpha-cateinin that occurs in the cell. This process can be reversed by dephosphorylation of beta-catenin (5). Applications: Suitable for use in ELISA, Western Blot, Immunoprecipitation and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-2ug/ml detects a band ~88kD in treated mouse embryonic cell lysate and HEK293 whole cell lysate. Immunohistochemistry: 1-2ug/ml Immunoprecipitation: 3-5ug/extract from 10e6 cells Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
