Allgemeine Beschreibung

Lysozyme is abundantly found in animal and plant kingdoms. It is a natural food preservative and also found to be present in specific bacterial cell walls. Lysozyme is usually present in tears, milk, urine and saliva.

Anwendung

Lysozyme from human neutrophils has been used in the checkerboard method for establishing a synergy between peptidomimetic 1 and immune effector molecules against E. coli.

Biochem./physiol. Wirkung

Lysozymes participates in the defense mechanism. It has the ability to stimulate catalysis by bringing steric stress in the substrates.

Einheitendefinition

One unit will lyse 0.6 μg of Micrococcus lysodeikticus per minute by turbidimetric detection at 600 nm when suspended in buffer at pH 6.2 at 25 °C.

Physikalische Form

Lyophilized from 50 mM sodium acetate, pH 6.0, with 100 mM NaCl
