Used in research settings to quantify levels of surfactant protein B (SP-B) in biological samples, particularly from bovine lung sources. This ELISA kit enables scientists to study lung function and surfactant metabolism in respiratory conditions. It is commonly applied in veterinary research, pulmonary disease studies, and pharmaceutical development to assess alveolar stability and immune responses in the lung. The assay supports high-throughput analysis with reliable sensitivity, making it suitable for monitoring changes in SP-B during infection, injury, or treatment.
