Capillary gel electrophoresis for rapid, high resolution DNA sequencing

Open access
Swerdlow, Harold, Gesteland, Raymond·1990·Nucleic Acids Research

Abstract

Capillary gel electrophoresis has been demonstrated for the separation and detection of DNA sequencing samples. Enzymatic dideoxy nucleotide chain termination was employed, using fluorescently tagged oligonucleotide primers and laser based on-column detection (limit of detection is 6,000 molecules per peak). Capillary gel separations were shown to be three times faster, with better resolution (2.4 x), and higher separation efficiency (5.4 x) than a conventional automated slab gel DNA sequencing instrument. Agreement of measured values for velocity, resolution and separation efficiency with theory, predicts further improvements will result from increased electric field strengths (higher voltages and shorter capillaries). Advantages of capillary gel electrophoresis for automatic DNA sequencing instruments and for genomic sequencing are discussed.

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.
