Trypsin from porcine pancreas is widely used in biological research and industrial applications. In cell culture, it is employed to detach adherent cells from surfaces, facilitating subculturing and experimental procedures. The enzyme is also utilized in protein digestion for mass spectrometry analysis, helping to break down proteins into smaller peptides for identification and characterization. In the food industry, it aids in the processing of proteins, enhancing texture and flavor in products like meat tenderizers. Additionally, trypsin is used in the production of insulin and other biopharmaceuticals, where it assists in the precise cleavage of peptide bonds during protein purification and modification processes. Its role in tissue dissociation further supports studies in developmental biology and regenerative medicine.
