Used in biomedical research to quantitatively measure E-cadherin protein levels in rat tissue extracts and biological fluids. This kit is particularly valuable in studies related to cell adhesion, epithelial-mesenchymal transition (EMT), cancer metastasis, and tissue integrity. Researchers use it to investigate diseases involving disrupted cell-cell adhesion, such as carcinomas and inflammatory conditions. It is also applied in toxicology studies to assess epithelial damage in organs like the liver, kidney, and lungs. The assay supports high-throughput analysis and provides a reliable tool for monitoring disease progression or treatment effects in experimental models.
