Used to measure soluble P-selectin levels in biological samples such as plasma or serum from rabbits. This assay is commonly applied in research settings to study platelet activation and endothelial cell function, particularly in inflammatory and thrombotic conditions. It helps investigate diseases involving vascular inflammation, atherosclerosis, and coagulation disorders in rabbit models. The kit enables quantitative detection, supporting studies in cardiovascular research, immunology, and drug development where monitoring P-selectin serves as a biomarker for cellular adhesion and vascular injury.
