Abstract
A novel method of spatial compression of a DNA sample inside the capillary for the gel capillary electrophoresis and an article for operating the method are disclosed. In this method, after the electrokinetic injection, the sample is compressed using the reverse electric field. A special DNA barrier material is used to contain the sample in the capillary. We expect that this Electro Static Compression (ESC) can increase the DNA concentration in the capillary by orders of magnitude. In the proposed method and article the injection and compression of the DNA sample are followed by subsequent electrophoretic separation in any kind of sequencing container (for instance glass capillary). The use of the ESC method will allow the increase of the length and the quality of the read, as well as reduction of the DNA consumption. ESC method will also permit the use of low power illumination sources including miniature and inexpensive light emitting diodes (LED) instead of the Ar-ion laser for exciting fluorescent labels in 4-color DNA sequencing.
