This product can also be used to measure lysozyme activity in yeast and bacteria. The assay is based on the ability of lysozyme to cleave a synthetic substrate and release a free fluorophore which can be easily quantified at Ex\/Em= 360\/445 nm in a fluorescent microplate reader.\u003cbr\u003e\nThis kit provides a simple, ultra-sensitive assay that can detect as low as 2 uU\/mL of Lysozyme activity.\u003cbr\u003e\nOther Notes\u003cbr\u003e\nThis product was previously called K236 Biovision Lysozyme Activity Assay Kit (Fluorometric). Biovision was acquired by Abcam in 2021.\u003cbr\u003e\nLysozyme (EC 3.2.1.17), also known as muramidase or N-acetylmuramide glycanhydrolase, is a hydrolase acting on glycosidic bonds. It hydrolyzes the Beta-(1-4)-glucosidic linkage between N-acetyl-muraminic acid and N-acetyl-D-glucosamine residues present in the mucopolysaccharide cell wall. Lysozyme is ubiquitously found in a wide range of biological fluids such as tears, saliva and tissues. It exhibits antibacterial, antitumor and immune modulatory activities. Elevated concentrations of lysozyme in urine and serum have been reported in patients suffering leukemia, tuberculosis, megaloblastic anemias, acute bacterial infections, ulcerative colitis, severe renal insufficiency, pyelonephritis and nephritis.\u003cbr\u003e\nThe Safety Datasheet for this product has been updated for certain countries.

The molecular weight of lysozyme is approximately 14 kDa. This protein is expressed in various tissues and body fluids including egg whites human saliva tears and milk. Lysozyme acts as an antimicrobial agent and plays a significant role in the innate immune system.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nLysozyme contributes to host defense by targeting bacteria. It is not part of a complex but functions as a single enzyme. By compromising the integrity of bacterial cell walls it clears pathogens swiftly from the body. Lysozyme activity assays measure its ability to hydrolyze bacterial peptidoglycan reflecting its role in immune defense. Many cells such as neutrophils and macrophages express lysozyme during the immune response aiding in pathogen clearance.\u003cbr\u003e\nPathways\u003cbr\u003e\nLysozyme is chiefly involved in the antibacterial humoral response pathway. Its action aligns with other antimicrobial proteins such as lactoferrin. Both lysozyme and lactoferrin are integral to the body's first line of defense against bacterial invasion. In addition lysozyme is relevant in the pathway managing mucosal immunity working in conjunction with proteins that enhance pathogen clearance like defensins.\u003cbr\u003e\nLysozyme has links to conditions such as sarcoidosis and hereditary renal amyloidosis. In sarcoidosis altered expression patterns of lysozyme may serve as a marker for disease activity. In hereditary renal amyloidosis mutations in the lysozyme gene result in amyloid fibril formation leading to renal dysfunction. Understanding these connections helps in the diagnosis and treatment of related conditions.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843631435945,"sku":"ab211113","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab211113","provider":"Iright","version":"1.0","type":"link"}
