Used in biomedical research to measure levels of coagulation factor VII in rat plasma or serum samples. This assay helps in studying blood clotting mechanisms, evaluating coagulation disorders, and assessing the effects of anticoagulant or procoagulant drugs in preclinical animal studies. It is particularly useful in thrombosis research, liver function studies, and drug development where accurate quantification of factor VII activity is required. The kit enables high-throughput analysis with high specificity and sensitivity, making it suitable for laboratory research in pharmacology, hematology, and toxicology.
