Single primer amplification (SPA) of cDNA for microarray expression analysis

Single primer amplification (SPA) of cDNA for microarray expression analysis.

The potential of expression analysis using cDNA microarrays to address complex problems in a wide variety of biological contexts is now being realised. A limiting factor in such analyses is often the amount of RNA required, usually tens of micrograms. To address this problem researchers have turned to methods of improving detection sensitivity, either through increasing fluorescent signal outpu...

RNA amplification strategies for cDNA microarray experiments.

The biological materials available for cDNA microarray studies are often limiting. Thus, protocols have been developed to amplify RNAs isolated from limited amounts of tissues or cells. RNA amplification by in vitro transcription is the most widely used among the available amplification protocols. Two means of generating a dsDNA template for the RNA polymerase are a combination of reverse trans...

An improved single-cell cDNA amplification method for efficient high-density oligonucleotide microarray analysis

A systems-level understanding of a small but essential population of cells in development or adulthood (e.g. somatic stem cells) requires accurate quantitative monitoring of genome-wide gene expression, ideally from single cells. We report here a strategy to globally amplify mRNAs from single cells for highly quantitative high-density oligonucleotide microarray analysis that combines a small nu...

cDNA MICROARRAY TECHNOLOGY FOR THE ANALYSIS OF GENE EXPRESSION

DNA microarray technology is a new and powerful tool for studying a genome-wide gene expression in many organisms. This technology is a high throughput, highly parallel RNA expression assay technique that permits quantitative analysis of RNAs transcribed from both known and unknown genes. This review describes array manufacturing, experimental design, and its application to gene discovery and e...
