Researchers rein in regulatory RNAs

...e transcripts. Employing a custom-made microarray chip designed to detect strand-specific expression of 1947 SAT pairs, the researchers discovered that most of the SATs were widely expressed in mouse brain, heart, and testis, as well as in mouse embryonic stem cells and fibroblasts. While some SATs were ...

Purdue researchers use enzyme to clip 'DNA wires'

... for precisely placing strands of DNA on a silicon chip and then stretching out the strands so that their encoded information might be read more clearly. The current work by Ivanisevic's team builds on that previous research. Kinsella created the magnetic particles, which are made from a ceramic iron oxi...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...p. The genetic sequence of the DNA tethered to the chip is known. Then researchers add a sample with an unknown composition of fluorescently labeled DNA molecules. The base pairs in the sample's single-stranded DNA, groups of which correspond to individual genes, stick to similar, or homologous, regions o...

New technique may speed DNA analysis

...n is found on a DNA microarray, a silicon or glass chip printed with up to 500,000 tiny dots. Each dot comprises multiple DNA molecules of known sequence, i.e. a piece of an individual's genetic code. Scientists use DNA microarrays to discover and analyze a person's DNA or messenger-RNA genetic code. This...
