Abstract

We have developed a method to accurately determine (< 3% RSD) the complete major and modified base composition of a few micrograms of unlabeled DNA. The DNA samples were quantitatively hydrolyzed with DNase 1, Nuclease P1, and bacterial alkaline phosphatase. The resulting deoxyribonucleosides were directly separated in 70 min by reversed-phase high performance liquid chromatography with detection by ultraviolet absorption at 254 nm and 280 nm (RP-HPLC). The highly sensitive and selective dual wavelength quantitation greatly enhances the precision and accuracy of the chromatographic analysis. Contamination of DNA preparations with RNA does not interfere with the DNA analysis due to the high resolution of the chromatography. We have used this method for the quantitation of m5dCyd in 5 microgram of calf thymus and salmon sperm DNA in which the m5dCyd comprises only 1 to 2% of the total bases. This method should be a useful research tool in studies on various DNAs and DNA subfractions and should help to elucidate the functions of methylation of DNA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
