Abstract

Neutrophils play a key role in the defense against microbial infections. One of their primary weapons to destroy microbes is the production of reactive oxygen species (ROS). This paper shows how 2', 7'-dichlorodihydrofluorescein-diacetate (DCFH-DA) was used to measure the effects of polysaccharides on the production of ROS by polymorphonuclear leukocytes (PMNs). The DCFH-DA method has been designed to provide a highly sensitive, quantifiable, real-time assessment of ROS production by PMNs.

摘要

中性粒细胞在抵御微生物感染中发挥关键作用。它们破坏微生物的主要武器之一是产生活性氧(ROS)。本文展示了如何使用2',7'-二氯二氢荧光素二乙酸酯(DCFH-DA)来测量多糖对多形核白细胞(PMN)产生活性氧的影响。DCFH-DA方法旨在对PMN产生活性氧进行高度灵敏、可量化的实时评估。
