One way they do this is to use a DNA microarray to determine the expression levels of genes. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate ...

While DNA microarrays are the most common, there is increasing utilization of protein, peptide and glycan microarrays. Structure of a DNA microarray Samples are arranged on the array in spots of ...

First, it is eminently feasible—DNA microarrays make it easy to measure the transcripts for every gene at once (much as we might wish to be able to measure the abundance of the final products of ...

DNA microarray (gene chip, DNA chip, or biochip) is one such technology that either measures DNA or uses DNA as a part of its detection system. In each of the spots in this array, a known DNA ...

DNA microarrays monitor the behavior of thousands of genes over time by detecting changes in the expression of as many as 30,000 different genes on one small chip.

Because of their huge scanning capability, DNA microarrays can drive R&D programs that would have been impossible before the advent of this technology. Southern blotting, now over three decades ...

Based on electrostatic repulsion that yields images visible to the naked eye, the technique could revolutionize the use of DNA microarrays for both research and diagnostics. The dream of ...

To compare all the genes of one organism to those of another organism, we must first know how to define the entire gene sequence of each organism. However, looking at all of an organism's genes ...

Central to microarray analysis for determining gene expression is the hybridization of fluorescently labeled RNA with a short strand of complementary DNA that is tethered to a solid surface ...

"We believe this technique could revolutionize the use of DNA microarrays for both research and diagnostics." Groves, who is also a Howard Hughes Medical Institute (HHMI) investigator, and members ...
