Used in biomedical research to measure soluble E-selectin levels in biological samples such as serum, plasma, or cell culture supernatants. This kit helps assess endothelial activation and inflammation in studies related to cardiovascular diseases, sepsis, diabetes, and autoimmune disorders. It is a valuable tool for researchers investigating vascular injury, atherosclerosis, or the effectiveness of anti-inflammatory treatments. The assay provides a sensitive and specific way to quantify sE-selectin, supporting both clinical and experimental investigations into endothelial function and disease progression.
