Used in biomedical research to detect and quantify P-selectin (GMP-140), a marker of platelet and endothelial cell activation. Helps assess thrombotic conditions, inflammation, and vascular injury in experimental models. Commonly applied in studies related to atherosclerosis, diabetes, sepsis, and autoimmune diseases. Provides a reliable method for measuring soluble P-selectin levels in plasma samples, aiding in understanding platelet degranulation and adhesion processes.
