What Are Tissue Microarrays?

DNA microarray is also called Oligonucleotide array, which is the product of the gradual implementation of the Human Genome Project (HGP) and the rapid development and application of molecular biology. Computer chip manufacturing and widely applied inspiration, a new technology developed on the basis of the original nucleic acid hybridization (Northern, Southern), integrating microelectronics, life sciences, computer science and photoelectrochemistry. It is the third One of the main technologies in the Second Revolution (Genome Revolution) is one of the biochips. The principle of this technology is to integrate gene probes of known sequence on a solid surface, and a large number of labeled nucleic acid sequences in the cells or tissues of the tested organism are hybridized with the above-mentioned probe arrays. By detecting the hybridization probes at the corresponding positions, gene information is achieved. Quick check.
