Used in biomedical research to quantify levels of pig secreted leukocyte protease inhibitor in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study the role of SLPI in inflammatory processes, immune regulation, and host defense mechanisms in porcine models. It is particularly useful in veterinary research, infectious disease studies, and translational medicine where pig models are used to mimic human physiological conditions. The assay supports investigation into lung inflammation, wound healing, and responses to bacterial or viral infections due to SLPI’s anti-protease and antimicrobial properties.
