Description

• General description: 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.[1]
• Application: 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.[2]
• Biochem/physiol Actions: Lysozymes participates in the defense mechanism. It has the ability to stimulate catalysis by bringing steric stress in the substrates.[1]
• Unit Definition: One unit will produce a ΔA450 of 0.001 per min at pH 6.24 at 25°C, using a suspension of Micrococcus lysodeikticus as substrate, in a 2.6 mL reaction mixture (1 cm light path).
• Physical form: Lyophilized from 50 mM sodium acetate, pH 6.0, with 100 mM NaCl
