Used in biomedical research to detect and quantify serine protease enzyme activity in human biological samples such as serum, plasma, and cell culture supernatants. Widely applied in studies related to inflammation, immune response, and tissue remodeling due to the role of serine proteases in these processes. Helps researchers investigate diseases like chronic obstructive pulmonary disease (COPD), cystic fibrosis, and certain cancers where dysregulation of serine protease activity is implicated. The kit enables high-throughput analysis in clinical and preclinical settings, supporting biomarker discovery and therapeutic development.
