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 diseases. Commonly applied in studies related to atherosclerosis, sepsis, diabetes, and autoimmune disorders. Enables researchers to measure soluble P-selectin levels in plasma samples, providing insight into disease progression and response to treatment. Widely used in clinical laboratories and pharmaceutical research for biomarker analysis.
