Used in biomedical research to quantify levels of Tissue Factor Pathway Inhibitor (TFPI) in human plasma or serum samples. This assay helps investigate the regulation of blood coagulation, particularly in studies related to thrombosis, hemostasis, and cardiovascular diseases. Researchers use the kit to assess TFPI concentration changes in clinical samples, enabling insights into anticoagulant pathways and potential therapeutic targets. It is also applied in drug development and evaluation of treatments affecting the coagulation cascade.
