The present invention provides methods, compositions and kits for detecting the presence or absence of an integrated insertion polynucleotide.

DNA recombination junction detection

A dry composition comprising a nucleotide linked to a fluorescent dye is provided. A method of making a dry composition comprising the step of drying a solution comprising a nucleotide linked to a fluorescent dye is provided. A method is provided for performing a reaction on a nucleic acid substrate comprising: (a) providing a vessel containing a dried composition comprising a nucleotide linked to a fluorescent dye, and (b) adding to the vessel an aqueous solution and the nucleic acid substrate. A kit is provided for determining the sequence of a nucleic acid, the kit comprising a dry composition comprising a nucleotide linked to a fluorescent dye.

Method for drying dye-terminator sequencing reagents

An electrophoretic method for purifying a nucleic acid sample is disclosed. According to the method, the electrophoresis is effective to substantially reduce the concentration of contaminants relative to the concentration of desired nucleic acid in the nucleic acid sample, thereby producing a purified nucleic acid. In the method, the loading and recovery wells may be the same or different, and the electric fields may be DC or alternating.

Electrophoretic nucleic acid purification method

An electrophoretic method for purifying a nucleic acid sample is disclosed. The method generally comprises the steps of (1) providing a nucleic acid sample comprising a desired nucleic acid and one or more contaminants, (2) providing an electrophoresis matrix having a loading well and a recovery well formed therein, (3) placing the nucleic acid sample into the loading well, (4) performing a first electrophoresis comprising electrophoresing the nucleic acid sample for a first time effective to transport the desired nucleic acid out of the loading well and into the electrophoresis matrix; and (5) performing a second electrophoresis comprising electrophoresing the nucleic acid sample for a second time effective to transport the desired nucleic acid out of the electrophoresis matrix and into the recovery well. According to the method, the first and second electrophoresis steps are effective to substantially reduce the concentration of contaminants relative to the concentration of desired nucleic acid in the nucleic acid sample, thereby producing a purified nucleic acid. In the method, the loading and recovery wells may be the same or different, and the electric fields may be DC or alternating. Also disclosed is a preparative electrophoresis method employing an alternating electrical field.
