Copper-phenanthroline-induced site-specific oxygen-radical damage to DNA. Detection of loosely bound trace copper in biological fluids.
Ontology highlight
ABSTRACT: Copper(II) ions, in the presence of 1,10-phenanthroline, O2 and a reducing agent, degrade DNA with the release of thiobarbituric-acid-reactive material. This reaction, dependent on the formation of oxygen radicals, was made the basis of a sensitive and specific assay for loosely bound copper in body fluids. When applied to certain extracellular fluids, trace amounts of copper could be detected in the lower micromolar range.
