2',7'-Dichlorodihydrofluorescein as a fluorescent probe for reactive oxygen species measurement: Forty years of application and controversy.

abstract：:We have here investigated possible occurrence of bicarbonate-dependent, carbonate radical anion (CO(3)(•-))-driven tocopherol-mediated human LDL peroxidation (TMP) in vitro and in vivo. CO(3)(•-), generated in vitro by the SOD1/H(2)O(2)/bicarbonate system, readily promoted TMP, which was dependent on α-tocopherol and ...
