[Measurements of salivary lysozyme activity]

A new method for measuring salivary lysozyme is proposed, which is based on lysozyme capacity to lyze glycosaminoglycanes and proteoglycanes in plasma membranes of Micrococcus lysodeikticus. Specific activity of the enzyme is identified from the amount of protein in glycosaminoglycanes and proteoglycanes. The quantity of glycosaminoglycanes and proteoglycanes containing 0.001 mg protein/ml/min is suggested to be takes as a unit of lysozyme.
