Mucin derived from bovine submaxillary gland is widely used in biomedical research and pharmaceutical applications due to its unique properties. It serves as a model glycoprotein for studying mucin structure and function, particularly in understanding mucus behavior and its role in protecting epithelial surfaces. This mucin is also employed in the development of drug delivery systems, where it enhances the bioavailability and stability of therapeutic agents by mimicking natural mucus barriers. Additionally, it is utilized in the production of artificial saliva and tear substitutes, providing lubrication and moisture retention in dry mouth and eye conditions. Its biocompatibility makes it suitable for use in tissue engineering and regenerative medicine, where it aids in creating scaffolds that promote cell adhesion and growth. Furthermore, it is used in cosmetic formulations to improve skin hydration and texture.
