Used for the quantitative detection of human elastase in biological samples such as serum, plasma, and cell culture supernatants. This ELISA kit is widely applied in research settings to study inflammatory processes, particularly in conditions like chronic obstructive pulmonary disease (COPD), cystic fibrosis, and other neutrophil-mediated inflammatory diseases. It enables researchers to measure elastase levels accurately, helping assess neutrophil activation and degranulation. The kit supports investigations into tissue remodeling, lung injury, and the effectiveness of anti-inflammatory compounds. It is not intended for diagnostic use but serves as a valuable tool in biomedical research and drug development.
