Description

Lysozyme is a naturally occurring enzyme, also known as muramidase, which functions as an antimicrobial agent by catalyzing the hydrolysis of 1,4-β-linkages in bacterial cell walls. This product, Lysozyme CAS NO 12650-88-3, is valued for its high purity and consistent biological activity, making it a critical ingredient in applications demanding reliable performance. It is essential for manufacturers in the pharmaceutical, food preservation, and biotechnology research sectors.

Application

• As a natural preservative and antimicrobial agent in cheese production and other dairy products.
• An active pharmaceutical ingredient (API) in certain ophthalmic solutions and throat lozenges for its antibacterial properties.
• A key reagent in biochemical research and cell biology for studying bacterial cell wall structure and lysis.
• Used in diagnostic kits and as a model protein in enzymology studies.
• Application in cosmetic formulations for its purported skin-conditioning benefits.
• As a processing aid in the extraction of intracellular components from Gram-positive bacteria.
