Magnetic bead purification of labeled DNA fragments for high-throughput capillary electrophoresis sequencing.
نویسندگان
چکیده
We have developed an automated purification method for dye-terminator-based DNA sequencing products using a magnetic bead approach. This 384-well protocol generates sequence fragments that are essentially free of template DNA, salt, and excess dye-terminator products. In comparison with traditional ethanol precipitation protocols, this method uses no centrifugation, is rapid, completely automated, and increases the phred-20 read length by an average of 40 bases. To date, we have processed over 4 million samples with 94% averaging 641 phred-20 bases on the MegaBACE 1000 and 4000 and the ABI PRISM 3700 capillary instruments.

Automated one-step DNA sequencing based on nanoliter reaction volumes and capillary electrophoresis.
An integrated system with a nano-reactor for cycle-sequencing reaction coupled to on-line purification and capillary gel electrophoresis has been demonstrated. Fifty nanoliters of reagent solution, which includes dye-labeled terminators, polymerase, BSA and template, was aspirated and mixed with the template inside the nano-reactor followed by cycle-sequencing reaction. The reaction products we...
متن کاملGlass bead purification of plasmid template DNA for high throughput sequencing of mammalian genomes.
To meet the new challenge of generating the draft sequences of mammalian genomes, we describe the development of a novel high throughput 96-well method for the purification of plasmid DNA template using size-fractionated, acid-washed glass beads. Unlike most previously described approaches, the current method has been designed and optimized to facilitate the direct binding of alcohol-precipitat...
متن کاملStrategies and Clinical Applications of Next Generation Sequencing
Abstract DNA sequencing is one of the great valuable techniques in molecular biology, which can be used to detect the sequence of nucleotides in a DNA fragment. The high-throughput sequencing known as Next Generation Sequencing (NGS) revolutionized genomic research and molecular biology; therefore, the whole human genome can be sequenced with a low cost in several days. NGS technology is simi...
متن کاملFootprinting with an automated capillary DNA sequencer.
Footprinting is a valuable tool for studying DNA-protein contacts. However, it usually involves expensive, tedious and hazardous steps such as radioactive labeling and analyses on polyacrylamide sequencing gels. We have developed an easy four-step footprinting method involving (i) the generation and purification of a PCR fragment that is fluorescently labeled at one end with 6-carboxyfluorescei...
متن کاملThe influence of fluorescent dye structure on the electrophoretic mobility of end-labeled DNA.
Over the past 10 years, fluorescent end-labeling of DNA fragments has evolved into the preferred method of DNA detection for a wide variety of applications, including DNA sequencing and PCR fragment analysis. One of the advantages inherent in fluorescent detection methods is the ability to perform multi-color analyses. Unfortunately, labeling DNA fragments with different fluorescent tags genera...
