| LZM

Lysozyme (LZM) is an antimicrobial enzyme produced by animals that forms part of the innate immune system. Peptidoglycan is the major component of gram-positive bacterial cell wall. This hydrolysis in turn compromises the integrity of bacterial cell walls causing lysis of the bacteria. Lysozyme is abundant in secretions including tears, saliva, human milk, and mucus. The enzyme functions by hydrolyzing glycosidic bonds in peptidoglycans. The enzyme can also break glycosidic bonds in chitin, although not as effectively as true chitinases.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	80	40	20	10	5	2.5	1.25	0
OD	2.32	1.89	1.4	0.97	0.58	0.37	0.22	0.07
Corrected OD	2.25	1.82	1.33	0.9	0.51	0.3	0.15	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Human LZM spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-101	96
Plasma(n=8)	92-105	102

 

| Linearity

Samples were spiked with high concentrations of Human LZM and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)
1 : 2	Range (%)	84-95	88-96
	Average (%)	91	93
1 : 4	Range (%)	88-103	87-108
	Average (%)	94	98
