Used in biomedical research to measure soluble E-selectin levels in human serum, plasma, or cell culture samples. Helps assess endothelial cell activation and inflammation in studies related to atherosclerosis, sepsis, diabetes, and autoimmune diseases. Enables researchers to investigate vascular dysfunction and monitor disease progression or response to treatment in clinical and preclinical settings. Widely applied in immunology and cardiovascular research for its high sensitivity and specificity in detecting low concentrations of sE-selectin.
