BACKGROUND There is extensive variation in gene expression among individuals within and between populations. Accurate measures of the variation in mRNA expression using microarrays can be confounded by technical variation, which includes variation in RNA isolation procedures, day of hybridization and methods used to amplify and dye label RNA for hybridization. METHODOLOGY/PRINCIPAL FINDINGS I...
Crested wheatgrass (Agropyron cristatum L.) breeding programs aim to develop later maturing cultivars for extending early spring grazing in Western Canada. Plant maturity is a complex genetic trait, and little is known about genes associated with late maturity in this species. An attempt was made using RNA-Seq to profile the transcriptome of crested wheatgrass maturity and to analyze differenti...
An efficient strategy for large-scale high-throughput transposon-mediated sequencing of cDNA clones.
We describe an efficient high-throughput method for accurate DNA sequencing of entire cDNA clones. Developed as part of our involvement in the Mammalian Gene Collection full-length cDNA sequencing initiative, the method has been used and refined in our laboratory since September 2000. Amenable to large scale projects, we have used the method to generate >7 Mb of accurate sequence from 3695 cand...
Low abundance mRNAs are more difficult to examine using microarrays than high abundance mRNAs due to the effect of concentration on hybridization kinetics and signal-to-noise ratios. This report describes the use of low complexity representations (LCRs) of mRNA as the targets for cDNA microarrays. Individual sequences in LCRs are more highly represented than in the mRNA populations from which t...
A rapid and versatile method for cDNA library construction was developed. It is based on conventional cDNA library synthesis including all enzymatic steps usually required, but is performed on a solid support. The cDNA is immobilised via a biotin residue to streptavidin coupled magnetic beads, which allows rapid and easy to perform changes of buffers and enzymes. Therefore, it combines speed (l...
Massively parallel DNA sequencing of thousands of samples in a single machine-run is now possible, but the preparation of the individual sequencing libraries is expensive and time-consuming. Tagmentation-based library construction, using the Tn5 transposase, is efficient for generating sequencing libraries but currently relies on undisclosed reagents, which severely limits development of novel ...
Complementary DNA (cDNA) is valuable for investigating protein structure and function in the research of life science, but it is difficult to obtain by traditional reverse transcription. In this study, we employed a novel strategy to clone the human leukemia inhibitory factor (hLIF) gene cDNA from genomic DNA directly isolated from the mucous membrane of mouth. The hLIF sequence can be acquired...
The fluorescently labelled short octameric oligothymine sequences of DNA, PNA and PCNA were used in fluorescence quenching studies in conjunction with dispersed graphene oxide. The measurable restoration of their fluorescence by complementary oligodeoxyadenylate was compared. This is the first study aimed at replacing the natural DNA probes with synthetic DNA mimics that show excellent properti...
Complementary DNA (cDNA) specific for gamma-globin nucleotide sequences has been prepared by hybridizing total cDNA made from cord blood messenger RNA (mRNA) as template to an excess of normal adult human globin mRNA and recovering the single-stranded cDNA from hydroxylapatite. The specificity of the gamma cDNA for gamma mRNA sequences is strongly supported by the hybridization of this cDNA at ...
Now a days, genome analysis has employed a rapid analysis tool known as expressed sequence tags. In 1983, SD Putney for the first time demonstrated the use of cDNA in identification of genome. The term expressed sequence tags (ESTs) was coined by Anthony Kerlavage at the Institute for Genomic Research. In 1991, Mark Adams used EST in relation to gene discovery and Human Genome project. cDNA or ...
