β-catenin (rat) ELISA Kit

β-catenin (cadherin-associated protein beta, 88 kDa) is a dual function protein, regulating the coordination of cell-cell adhesion and gene transcription via the Wnt signaling pathway. Mutations and overexpression of β-catenin are associated with many cancers, including hepatocellular, colorectal, lung, breast, ovarian and endometrial cancers. BioVision"s rat β-catenin ELISA Kit is based on the standard principle of a sandwich enzyme-linked immunosorbent assay. Rat β-catenin antibody is coated on a 96-well plate. Standards and test samples are added to the wells and β-catenin present in a sample is bound by the immobilized antibody. An HRP-conjugate reagent is added subsequently. After washing away the unbound antibody/HRP conjugates, HRP substrate TMB is used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue product that changes into yellow after adding acidic stop solution. The density of yellow color is proportional to the rat β-catenin captured onto the plate. This ELISA kit shows no species cross-reactivity. Detection Range: 5 - 240 ng/L.
