Used to measure inducible nitric oxide synthase (iNOS) activity in porcine biological samples such as cell lysates, tissue homogenates, and serum. Commonly applied in immunology and inflammation research to study immune responses, macrophage activation, and infectious diseases in pigs. Helps evaluate the effectiveness of anti-inflammatory drugs and vaccines by quantifying changes in iNOS levels. Suitable for high-throughput screening in veterinary research and biomedical studies involving porcine models.
