1. 🧪 Scientific Research and Experiments
• Proteomics Research:
Used for enzymatic digestion and hydrolysis of proteins, preparing samples for analysis.
As a serine protease, it can hydrolyze proteins and polypeptide chains.
• Biochemical Analysis:
Used in experimental techniques such as cell culture and ELISA (enzyme-linked immunosorbent assay).
Used as a tool enzyme in various bioanalytical techniques.
• Enzyme Activity Measurement and Analysis:
Used to measure the activity of elastase inhibitors, a common method for drug screening.
The effectiveness of inhibitors is assessed by detecting the degree to which their activity is inhibited.

2. 🐭 Animal Disease Model Construction
Construction of abdominal aortic aneurysm (AAA) models.
Elastase is infused into the abdominal aorta of rats through surgery to induce elastin degradation in the blood vessel wall, thereby simulating the pathological characteristics of human abdominal aortic aneurysm.

3. 💊 Clinical Medical Applications
• Treatment of Metabolic Diseases:
Used as an adjunct treatment for hyperlipidemia, atherosclerosis, and fatty liver.
It can activate lipoprotein lipase, regulate lipoprotein metabolism, and promote the conversion of cholesterol into bile acids.
• Pancreatic Function Diagnosis:
Detection of fecal elastase-1 (FE-1) is an important indicator for evaluating pancreatic exocrine function.
Low FE-1 concentration indicates severe pancreatic insufficiency.

4. 🍖 Food Industry
As a meat tenderizer: Used in the processing of meat and aquatic products to improve texture.
It utilizes its protein hydrolysis properties to degrade elastin and other components in muscle connective tissue.
