Used in biomedical research to measure AST (aspartate aminotransferase) enzyme activity in goat serum, plasma, or tissue samples. Helps assess liver and heart health in goats, particularly in veterinary diagnostics and livestock health monitoring. Commonly applied in studies involving liver injury, metabolic disorders, or toxicity evaluations in caprine models. Provides a quantitative and sensitive method for detecting changes in AST levels, supporting early disease detection and evaluation of treatment efficacy.
