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 ...

Microarrays come in two basic flavours: complementary DNA (cDNA) or oligonucleotide arrays. cDNA arrays can be obtained commercially on filters, or made on glass slides. To compare mRNA levels in ...

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 ...

Uses microarray-based autosomal DNA testing to examine a broad range of your genome (both maternal and paternal) to find comprehensive DNA matches and recent family history. Family tree linking ...

Microarray Scanners are devices used to measure the fluorescent areas of a DNA microarray to reveal information about the simultaneous activity of thousands of genes. This information can help ...

In light of the variety involved, the researchers decided to combine the method with DNA microarray technology, utilizing a multiplex approach with 14 reactions that take place simultaneously.

The device consists of lasers, a special microscope, and a camera. The DNA material in the microarray is labeled with fluorescents which become excited by the lasers in the scanner. The microscope and ...

Expert Rev Mol Diagn. 2013;13(6):601-611. In other situations, normal microarray analysis in the presence of an abnormal karyotype, such as marker chromosomes, is reassuring, as it indicates that ...

LuxScan 10K Microarray Scanner is a compact high performance system for microarray imaging and data analysis of DNA, protein and cell arrays. Its advanced systems for optics, signal processing and ...
