Elastase is widely used in biochemical research for its ability to break down elastin, a key protein in connective tissues. This property makes it valuable for studying tissue structure and function, particularly in understanding diseases related to elastin degradation, such as emphysema and atherosclerosis. In the medical field, elastase is utilized in wound care to remove damaged tissue and promote healing. It is also employed in the development of treatments for conditions involving abnormal elastin accumulation, such as certain types of fibrosis. Additionally, elastase plays a role in industrial applications, including the processing of animal tissues for bioproducts and the modification of proteins in food science to improve texture and digestibility.
