Used in biomedical research to quantify lactate dehydrogenase 3 (LDH3) levels in rat tissue samples and biological fluids. Helps assess cellular damage, particularly in tissues rich in LDH3 such as lungs, spleen, and platelets. Commonly applied in studies involving organ toxicity, inflammation, and apoptosis. Enables researchers to monitor disease progression and evaluate the efficacy of therapeutic interventions in rodent models. Provides a sensitive and specific method for detecting LDH3 isoenzyme without interference from other LDH isoforms.
