Used to measure 5-nucleotidase (5-NT) enzyme activity in chicken samples, particularly in research settings focused on liver function, metabolic disorders, and poultry health assessment. The kit enables quantitative analysis of 5-NT levels in serum, plasma, or tissue homogenates, supporting studies on hepatobiliary diseases and purine metabolism in avian species. It is commonly applied in veterinary diagnostics, agricultural research, and pharmaceutical development where monitoring enzyme activity helps evaluate organ function or treatment efficacy. The ELISA format allows high-throughput, sensitive, and specific detection, making it suitable for both experimental and clinical laboratories working with poultry models.
