该测定试剂盒利用一种创新性方法测量溶菌酶活性。使用的溶壁微球菌细胞壁已被荧光素广泛标记,从而导致荧光信号猝灭。活性溶菌酶可水解粘多糖细胞壁内 N-乙酰胞壁酸与 N-乙酰-D-葡糖胺残基之间的 b-(1-4)-糖苷键,从而消除猝灭并产生与溶菌酶活性成比例的显著荧光强度增加。

常见问题解答 (FAQ)

How can I limit signal saturation when using the EnzChek Lysozyme Assay Kit (Cat. No. E22013)?

To limit signal saturation when using the EnzChek Lysozyme Assay Kit (Cat. No. E22013), try lowering the voltage (gain) on the PMT (photomultiplier tube). If you are still seeing signal saturation after lowering the voltage, try a shorter reaction time, and/or lower substrate concentration.

How was the substrate (Component A) in the EnzChek Lysozyme Assay Kit labeled?

The primary amines on the cell wall of Micrococcus lysodeikticus were conjugated to fluorescein.

May other buffers be used for the EnzChek Lysozyme assay?

Yes. You may use other buffers that are compatible with the enzyme of interest. The buffer provided is optimal for use with chicken egg white lysozyme. If the buffer has a pH <6, adjust the pH to 7.5 to 8 prior to detection for optimal signal from the fluorescein. The emission of fluorescein drops off at pH <6.

Abstract
Vogesella mureinivorans sp. nov., a peptidoglycan-degrading bacterium from lake water.
Authors:Jørgensen NO, Brandt KK, Nybroe O, Hansen M,
Journal:Int J Syst Evol Microbiol
PubMed ID:19946047
'A novel, non-pigmented, rod-shaped, Gram-negative strain was isolated from mesotrophic lake water in Zealand, Denmark. Phylogenetic analysis of the 16S rRNA gene sequence of the bacterium, designated strain 389(T), indicated that the strain belonged to the genus Vogesella and formed a monophyletic group with Vogesella perlucida DS-28(T) (99.1?% nucleotide similarity); ... More
Structure-function analysis of HsiF, a gp25-like component of the type VI secretion system, in Pseudomonas aeruginosa.
Authors:Lossi NS, Dajani R, Freemont P, Filloux A,
Journal:Microbiology
PubMed ID:21873404
'Bacterial pathogens use a range of protein secretion systems to colonize their host. One recent addition to this arsenal is the type VI secretion system (T6SS), which is found in many Gram-negative bacteria. The T6SS involves 12-15 components, including a ClpV-like AAA(+) ATPase. Moreover, the VgrG and Hcp components have ... More
Mechanisms of systemic vasodilation by lysozyme-c in septic shock.
Authors:Gotes J, Kasian K, Jacobs H, Cheng ZQ, Mink SN,
Journal:J Appl Physiol (1985)
PubMed ID:22096116
In septic shock (SS), cardiovascular collapse is caused by the release of inflammatory mediators. We previously found that lysozyme-c (Lzm-S), released from leukocytes, contributed to systemic vasodilation in a canine model of SS. We then delineated the pathway by which this occurs in a canine carotid artery organ bath preparation ... More
Mutations of the Listeria monocytogenes peptidoglycan N-deacetylase and O-acetylase result in enhanced lysozyme sensitivity, bacteriolysis, and hyperinduction of innate immune pathways.
Authors:Rae CS, Geissler A, Adamson PC, Portnoy DA,
Journal:Infect Immun
PubMed ID:21768286
Listeria monocytogenes is a Gram-positive intracellular pathogen that is naturally resistant to lysozyme. Recently, it was shown that peptidoglycan modification by N-deacetylation or O-acetylation confers resistance to lysozyme in various Gram-positive bacteria, including L. monocytogenes. L. monocytogenes peptidoglycan is deacetylated by the action of N-acetylglucosamine deacetylase (Pgd) and acetylated by ... More
Alcohol use disorders affect antimicrobial proteins and anti-pneumococcal activity in epithelial lining fluid obtained via bronchoalveolar lavage.
Authors:Burnham EL, Gaydos J, Hess E, House R, Cooper J,
Journal:Alcohol Alcohol
PubMed ID:20729531
Our overall objective was to examine whether characteristics of epithelial lining fluid (ELF) from subjects with alcohol use disorders (AUDs) obtained via bronchoalveolar lavage (BAL) contribute to their predisposition to pneumococcal pneumonia. We sought to compare the anti-pneumococcal activity of acellular human BAL from subjects with AUDs to matched controls. ... More
