Purification of lysozyme from human neutrophils, and development of an ELISA for quantification in cells and plasma.
Lysozyme was purified from exocytosed granule material from PMA-stimulated human neutrophils by polyethyleneglycol precipitation, cation exchange chromatography and molecular sieve chromatography. Rabbit antibodies were biotinylated and affinity purified on a lysozyme column, for subsequent development of a novel ELISA. This ELISA for lysozyme is sensitive and accurate, and applicable to determination of lysozyme in neutrophils and plasma.
