Used in research settings to measure leptin concentration in biological samples from bovine sources. Helps in studying energy balance, appetite regulation, and metabolic health in cattle. Commonly applied in veterinary research, animal physiology studies, and agricultural science to understand obesity, reproduction, and lactation performance. Provides a reliable, sensitive method for quantifying leptin levels in serum, plasma, or cell culture supernatants. Supports investigations into nutritional management and metabolic disorders in dairy and beef cattle.
