Used in biological research to quantitatively measure β-catenin protein levels in rat tissue extracts, cell lysates, or biological fluids. This ELISA kit is particularly useful in studies related to the Wnt signaling pathway, which plays a critical role in cell proliferation, differentiation, and embryonic development. It is commonly applied in cancer research, especially in investigating tumor progression and metastasis where β-catenin signaling is dysregulated. The kit enables high-throughput analysis with high sensitivity and specificity, making it suitable for preclinical studies and molecular biology research in neuroscience, regenerative medicine, and developmental biology.
