Gene, Transcription Start Site and Splice Site Identification Increased Through Use of Automated Preparative Gel Electrophoresis

9 Sept 2013

Gel purification of cDNA and RNA-Seq libraries is the gold standard for purification options but these methods are time consuming and so most protocols have standardized on bead or column purification methods. This scientific poster compares two systems for library purification steps in NGS. The Pippin Prep, a preparative gel electrophoresis system, is shown to offer several advantages over other protocols for this application including efficient removal of low molecular weight library contaminants (primer/adapter artifacts) and accurate size-selection of the library.

Pippin Prep DNA Size Selection System

Sage Science

The Pippin Prep is a preparative electrophoresis platform for collection of size-selected DNA samples. The system automates DNA size selection using disposable, pre-cast agarose cassettes to extract fractions according to user-defined software input. Samples are electro-eluted from agarose and collected in buffer. The platform is used for the construction of next-gen sequencing libraries. The system collects fragments (depending on gel type) between 90 bp- 8kb. A higher quality of sample can be extracted, more reproducibly and with no cross-contamination, when compared to manual gel purification methods.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.

There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.DNA SequencingDNA sequencing, such as sanger sequencing, is a biological technique that determines the precise order of nucleotide bases in a fragment or template of DNA. DNA sequencers and genetic analyzers are based on capillary electrophoresis, where labeled DNA fragments are electrophoretically separated by size as they migrate through a polymer.
