ABSTRACT:
The DNA sequencing apparatus contains the following components. A first reaction vessel contains a reaction chamber into and out of which can be transferred reagents, reactants and reaction products. A device for separating individual oligonucleotides and polynucleotides on the basis of length, such as an electrophoretic unit, receives reaction products from the first reaction vessel. A second reaction vessel is designed for oxidizing pentose sugars. It comprises a reaction chamber having a device for transferring reactants and reagents into the reaction chamber and gaseous by-products of a reaction out of the reaction chamber. Separated oligonucleotides and polynucleotides can be selectably transferred from the separating device alternatively into the first or the second reaction vessel. The device also includes a second transfer device for transferring the gaseous by-products out of the second reaction vessel and a collection chamber for collecting the gaseous by-products. The collection chamber is in communication with the second transfer device. Finally, the apparatus contains an analyzer for analyzing the relative abundance of the components of the gaseous by-product by mass such as a mass spectrometer, the analyzer being in communication with a transfer device for transferring gaseous by-products from the collection chamber to the analyzer.
