Used in biomedical research to quantify levels of Protease Activated Receptor 4 (PAR4) in human samples, this ELISA kit supports studies related to platelet activation, thrombosis, and cardiovascular diseases. It enables researchers to investigate PAR4 expression in cell cultures, plasma, and serum, aiding in the development of antiplatelet therapies and understanding of coagulation disorders. The assay is also applied in pharmacological studies assessing drug effects on PAR4-mediated signaling pathways.
