Abstract

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.

摘要

通过聚乙二醇沉淀、阳离子交换色谱法和分子筛色谱法从经佛波酯(PMA)刺激的人中性粒细胞的胞吐颗粒物质中纯化溶菌酶。将兔抗体进行生物素化,并在溶菌酶柱上进行亲和纯化,以用于后续新型酶联免疫吸附测定(ELISA)的开发。这种溶菌酶ELISA灵敏且准确,适用于测定中性粒细胞和血浆中的溶菌酶。
