Used to measure levels of granulocyte macrophage colony-stimulating factor (GM-CSF) in pig biological samples such as serum, plasma, or cell culture supernatants. This kit is essential in immunological research involving pig models, helping to assess immune responses, inflammation, and macrophage activation. Commonly applied in veterinary research, vaccine development, and studies of infectious diseases in swine. Enables quantitative analysis of cytokine production, supporting evaluation of therapeutic interventions and immune system modulation in porcine experimental models.
