Used in biomedical research to detect and quantify broad-spectrum cytokeratins in human samples, this ELISA kit is particularly valuable in cancer studies, especially for identifying epithelial cell-derived tumors. It supports the investigation of tumor markers in body fluids such as serum, urine, or tissue culture supernatants, aiding in the early detection, monitoring, and prognosis of carcinomas including lung, breast, and gastrointestinal cancers. The assay is also applied in assessing cytokeratin release during cell apoptosis or necrosis, providing insights into tissue damage and therapeutic response in clinical and research settings.
