Used for the quantitative determination of melatonin levels in pig biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is specifically designed for research purposes in veterinary science, endocrinology, and animal physiology. It enables accurate measurement of melatonin concentrations to study circadian rhythms, reproductive cycles, stress responses, and seasonal breeding patterns in pigs. The assay supports high-throughput analysis and is commonly used in agricultural research to evaluate the impact of environmental factors, lighting regimens, or nutritional interventions on melatonin secretion. Results aid in optimizing swine management practices and improving animal welfare and productivity.
