Used to measure levels of interleukin-6 (IL-6) in biological samples such as serum, plasma, or cell culture supernatants from monkeys. It is commonly applied in immunology and infectious disease research to monitor inflammatory responses. Frequently used in preclinical studies to evaluate immune activation during viral infections, vaccine development, or autoimmune disease models involving non-human primates. Provides a reliable and sensitive method for quantifying cytokine production, helping researchers assess the efficacy of treatments or the progression of disease.
