DNA microarrays with stem–loop DNA probes: preparation and applications

Applications of DNA microarrays in biology.

DNA microarrays have enabled biology researchers to conduct large-scale quantitative experiments. This capacity has produced qualitative changes in the breadth of hypotheses that can be explored. In what has become the dominant mode of use, changes in the transcription rate of nearly all the genes in a genome, taking place in a particular tissue or cell type, can be measured in disease states, ...

Fabrication of DNA microarrays using unmodified oligonucleotide probes.

Microarrays printed on glass slides are often constructed by covalently linking oligonucleotide probes to a derivatized surface. These procedures typically require relatively expensive amine- or thiol-modified oligonucleotide probes that add considerable expense to larger arrays. We describe a system by which unmodified oligonucleotide probes are bound to either nonderivatized or epoxy-silane-d...

Preparation of functional DNA microarrays through laser-induced forward transfer

Comparison of probe preparation methods for DNA microarrays.

DNA microarrays and pharmacogenomics.

The DNA microarrays have proven to be a state of the art technique for high throughput comprehensive analysis of thousand of genes in parallel. The application of a DNA microarray to compare normal and pathological cells, tissues or organs may allow, along with classical positional cloning techniques, to speed up the discovery of genes and gene pathways implicated in several diseases. This in t...
