Used in biomedical research to measure levels of coagulation factor II (prothrombin) in rabbit plasma or serum samples. This ELISA kit enables accurate quantification of factor II concentration, supporting studies on blood coagulation mechanisms, anticoagulant drug development, and liver function in rabbit models. Commonly applied in preclinical research, especially in hematology and cardiovascular disease models where coagulation pathways are investigated. Provides a reliable, sensitive, and specific method for monitoring changes in prothrombin levels due to genetic, pharmacological, or pathological factors.
