Description	Lysozyme from chicken egg white is a bactericidal enzyme, and it lyses gram-positive bacteria. Lysozyme from chicken egg white can also be used for the research of HIV infection and pulmonary emphysema^[1]^[2]^[3].
IC₅₀ & Target	Bacteria^[1]
In Vitro	Lysozyme is an ubiquitous enzyme. The hen egg is the most abundant source of Lysozyme, which constitutes approximately 3.4% of the albumen proteins. Lysozyme is a natural antimicrobial that hydrolyzes the β(1-4) glycosidic linkage between N-acetylmuramic acid and N-acetylglucosamine found in the peptidoglycan layer of the bacterial cell wall and causing cell lysis. The bactericidal effect of Lysozyme is primarily limited to gram-positive bacteria, including pathogens such as Listeria monocytogenes and certain Clostridium species as well as some spoilage organisms, including thermophilic spore-forming bacteria and certain yeasts. The gram-negative bacteria are more resistant to Lysozyme action because of their complex cell wall structure^[1]. Lysozyme (1 mg/mL) impairs the ability of hyaluronan (HA) to prevent elastase injury to elastic fibers^[3]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods.

In Vivo	Syrian hamsters exposes to aerosolized Lysozyme (20 mg in 20 ml of water; 50 min) prior to elastase administration showes significantly increased airspace enlargement^[3]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Kinase Assay ^[1]	For measurement of lytic activity in egg white at each pH, temperature, and CO₂ condition, eggs are randomly selected from a flat of eggs (2 dozen eggs) obtained from a local grocery store. To determine the amount of egg white to be added to obtain a 0.001% lysozyme concentration, it is documented that chicken egg white contains approximately 3.4% lysozyme. For determining egg white activity, 0.030 g of albumen was added to 100 mL of the buffered solutions. This equated to a concentration of approximately 0.001% lysozyme. In addition, the egg white contains other antimicrobial proteins that are naturally present, as mentioned in the Introduction section^[1].
