Used in biomedical research to quantify fibrinogen levels in rat plasma or serum samples. Enables study of blood coagulation, inflammation, and fibrinolysis in experimental models. Commonly applied in cardiovascular research, toxicology studies, and evaluation of drug effects on hemostasis. Provides a reliable, sensitive, and specific measurement method through enzyme-linked immunosorbent assay (ELISA) technique. Suitable for high-throughput screening and longitudinal studies requiring precise protein detection.
