Used in biomedical research to quantify Endocan (ESM-1) levels in biological samples such as serum, plasma, or cell culture supernatants. The kit enables detection of endothelial cell activation and dysfunction, supporting studies in inflammation, sepsis, cancer progression, and cardiovascular diseases. It is widely applied in clinical research to evaluate biomarkers related to vascular pathology and tumor angiogenesis. The assay provides high sensitivity and specificity, making it suitable for monitoring disease states and therapeutic responses in experimental models and human studies.
