Porcine Surfactant Associated Protein A (SPA) ELISA Kit

Quantitative immunoassays for pulmonary biomarkers are essential tools in respiratory research, particularly when porcine models are used to investigate surfactant biology and lung disease. This ELISA kit from Assay Genie targets porcine Surfactant Associated Protein A (SP-A), a hydrophilic component of pulmonary surfactant involved in innate immunity, surfactant homeostasis, and respiratory defense mechanisms. Pig airways share close anatomical and biochemical similarity with human lungs, making porcine SP-A a relevant biomarker in studies of neonatal respiratory distress, alveolar injury, inhaled toxicology, and pulmonary inflammation. The colorimetric readout is compatible with standard microplate readers, and the 96-assay configuration integrates with routine laboratory workflows. It accommodates a range of sample matrices relevant to lung research, including tissue homogenates and lung lavage fluid, giving investigators flexibility in experimental design. Researchers can use the kit to support reproducible in vitro quantification of porcine SP-A in studies focused on pulmonary biology and respiratory disease mechanisms.
