Beschreibung

General description

Native lysozyme from human neutrophils. Occurs in specific granules of human polymorphonuclear leukocytes and takes part in antibacterial activity of leukocytes. Hydrolyzes β1,4 linkages between N-acetylmuramic acid (2-acetamido-2-deoxy-3-O-[1′-carboxymethyl]-glucopyranose) residues in chitin.

Physical form

Lyophilized from 100 mM NaCl, 50 mM sodium acetate buffer, pH 6.0.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short term storage. Stock solutions are stable for up to 3 days at 4°C or for up to 1 year at -20°C.

Prepared from blood that has been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.
