Used in biomedical research to measure soluble platelet endothelial cell adhesion molecule-1 (sPECAM-1) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit helps assess endothelial cell activation and vascular inflammation, making it valuable in studies related to cardiovascular diseases, atherosclerosis, diabetes, and autoimmune disorders. It enables researchers to monitor disease progression and evaluate the effectiveness of therapeutic interventions targeting vascular integrity and inflammation. The assay provides a sensitive and specific quantitative measurement, supporting both basic research and preclinical investigations.
