Used in biomedical research to quantify levels of surfactant protein B (SP-B) in lung tissue or biological fluids, this ELISA kit helps assess lung function and integrity of the pulmonary surfactant system. It is particularly valuable in studies related to respiratory distress syndrome (RDS), especially in premature infants, where SP-B deficiency is a key factor. Researchers also use it to investigate lung injuries, infections, and interstitial lung diseases. The kit enables high-throughput, sensitive detection, supporting both clinical diagnostics development and mechanistic studies in pulmonary biology.
