title: Using 2', 7'-dichlorodihydrofluorescein-diacetate to assess polysaccharides as immunomodulating agents.
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.
