Used in research to study proteolytic enzyme activity, particularly in breaking down elastin and other structural proteins in tissues. Commonly applied in cell isolation procedures, especially for dissociating tissues in primary cell culture. Helps in analyzing inflammatory processes, as elastase is involved in immune responses and tissue remodeling. Also used in assays to screen inhibitors of serine proteases, which has implications in treating diseases like emphysema, chronic obstructive pulmonary disease (COPD), and certain genetic disorders. The lyophilized form ensures stability for storage and transport, making it convenient for laboratory use.
