Specifications for β-Catenin Antibody, anti-human, REAdye_lease™


Clone REAL641 is an antibody fragment derived from the full β-Catenin antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAdye_lease Complex to bind markers with high avidity.
Clone REAL641 recognizes the human β-Catenin antigen, a 92 kDa dual function protein regulating the coordination of cell-cell adhesion and gene transcription. β-Catenin is a subunit of the cadherin protein complex and acts as an intracellular signal transducer in the Wnt signaling pathway. As a component of adherens junctions, β-catenin binds cadherins, Tcf family transcription factors, and the tumor suppressor APC. Mutations and overexpression of β-catenin are associated with many cancers, including hepatocellular carcinoma, colorectal carcinoma, lung cancer, malignant breast tumors, ovarian and endometrial cancer.
For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675).
