Used in research settings to quantify low molecular weight heparin (LMWH) concentrations in biological samples, particularly pig plasma or serum. Enables pharmacokinetic and pharmacodynamic studies of LMWH in porcine models, which are commonly used in cardiovascular and thrombosis research. Supports evaluation of anticoagulant therapy efficacy, drug development, and optimization of dosing regimens in veterinary or translational medicine. The ELISA format offers high sensitivity and specificity, allowing detection of LMWH fragments bound to anti-Factor Xa antibodies. Suitable for preclinical studies involving pigs as a model for human coagulation disorders.
