Used in biomedical research to measure E-selectin levels in biological samples such as serum, plasma, or cell culture supernatants. Helps assess endothelial cell activation and inflammation in conditions like atherosclerosis, sepsis, rheumatoid arthritis, and other inflammatory diseases. Commonly applied in studies related to vascular biology, immune response, and drug development to evaluate the effectiveness of anti-inflammatory treatments. Provides a reliable, sensitive, and quantitative method for detecting soluble E-selectin, aiding in both clinical research and laboratory investigations.
