Used in research settings to measure thrombin-antithrombin complex levels in rat plasma or serum, this ELISA kit helps assess coagulation activation and thrombotic potential in experimental models. It is commonly applied in studies related to thrombosis, inflammation, cardiovascular diseases, and anticoagulant drug development. The assay enables quantitative analysis of TAT levels, providing insight into the balance between pro-coagulant and anti-coagulant activities in vivo. Due to its species-specific design, it supports translational research using rat models to mimic human coagulation disorders.
