Protocol
Available protocols: Immunofluorescence (Frozen), Immunofluorescence (Immunocytochemistry), Flow Cytometry (Fixed/Permeabilized)
Specificity / Sensitivity
beta-Catenin (L54E2) Mouse Monoclonal Antibody (Alexa Fluor
Species Reactivity: Human, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the carboxy terminus of human β-catenin. The antibody was conjugated to Alexa Fluor 488 under optimal conditions with an F/P ratio of 2-5.
Background
β-catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8).
