Product details:
Human Lysozyme ELISA Kit ab267798 is a rapid single-wash 90-min Sandwich ELISA to measure Human Lysozyme in cell culture supernatant, EDTA plasma, heparin plasma, milk, saliva, serum, urine. This SimpleStep sensitivity is 7.31 pg/mL.
How the assay works
Human Lysozyme SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Lysozyme is an integral part of the innate immune system where it serves to hydrolyze the1,4-beta linkages of N-acetylmuramic acid and N-acetyl-D-glucosamine. This hydrolysis helps weaken the cell membrane of gram-positive bacteria. It is found in high abundance in secretory fluids, i.e tears, saliva, milk.

Lysozyme also known as muramidase is a protein with enzymatic activity that breaks down bacterial cell walls by hydrolyzing the glycosidic bonds of peptidoglycan. 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.
Biological function summary
Lysozyme 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.
Pathways
Lysozyme 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.
Lysozyme 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.
