WebMay 5, 2015 · To confirm whether age-dependent iron elevation is a catalytic source of the in vivo oxidative stress, we measured DCFH oxidation in the soluble fraction of lysed C. elegans. This ex vivo oxidative activity from wild type C. elegans increased throughout lifespan (two-tailed unpaired Student's t -test, p < 0.001; Fig. 2d ), matching the observed ... WebRate of dichlorofluorescin (DCFH) oxidation, an indication of intracellular oxidant production, was significantly higher in the homogenates of aged heart and liver compared with their young counterparts. In the isolated heart and liver mitochondria, ageing increased oxidant production by 29 and 32% (P<0.05), respectively.

WebThe molecule is oxidized to the fluorescent rhodamine123 ( λexcitation 505 nm and λemission 529 nm) and is trapped within cells in this form. Like DCFH, DHR is not oxidized by superoxide or H 2 O 2 alone, but can detect H … WebJan 10, 2003 · Dichlorodihydrofluorescein (DCFH) is one of the most frequently used probes for detecting intracellular oxidative stress. In this study, we report that H2O2-dependent intracellular oxidation of DCFH to a green fluorescent product, 2',7'-dichlorofluorescein (DCF), required the uptake of extracellular iron transported through a transferrin receptor …
WebThe compound 2',7'-dichlorofluorescin diacetate (DCFH-DA) is a probe for intracellular peroxide formation commonly used in such studies. During our studies we unexpectedly found that incubation of Trolox, a water soluble vitamin E analog, with DCFH-DA in cell-free physiological buffers resulted in the deacetylation and oxidation of DCFH-DA to ... WebThe oxidation of 2'7'-dichlorofluorescin (DCFH) to fluorescent 2'7'-dichlorofluorescein (DCF) is commonly used for the detection of radiation-induced ROS. The DCF …
