Определение microarray в Английский Язык Английский Язык словарь
- Any of several devices, containing a two-dimensional array of small quantities of biological material, used for various types of assay; the array itself
- Similar approach to the DNA chip, except that microarrays use cDNAs (EST clone inserts, for instance), and not oligonucleotides, and are immobilized on glass Quicker and cheaper when compared to DNA chips, but less precise
- (Biyoloji) A supporting material (as a glass or plastic slide) onto which numerous molecules or fragments usually of DNA or protein are attached in a regular pattern for use in biochemical or genetic analysis
- Sets of miniaturized chemical reaction areas that may also be used to test DNA fragments, antibodies, or proteins
- A tool used to sift through and analyze the information contained within a genome A microarray consists of different nucleic acid probes that are chemically attached to a substrate, which can be a microchip, a glass slide or a microsphere-sized bead
- An array of DNA or protein samples that can be hybridized with probes to study patterns of gene expression
- A very small, two dimensional array, typically on a glass, filter, or silicon wafer, upon which genes or gene fragments are deposited or synthesized in a high-density matrix, in a predetermined spatial order, allowing them to be made available to labeled probes in a high-throughput, parallel manner
- Tool for studying how large numbers of genes interact with each other and how a cell's regulatory networks control vast batteries of genes simultaneously Uses a robot to precisely apply tiny droplets containing functional DNA to glass slides Researchers then attach fluorescent labels to DNA from the cell they are studying The labeled probes are allowed to bind to cDNA strands on the slides The slides are put into a scanning microscope to measure ... how much of a specific DNA fragment is present [NHGRI]
- Any of several devices, containing a two-dimensional array of small quantities of biological material, used for various types of assay
- DNA microarray
- a collection of microscopic DNA spots attached to a solid surface forming an array; used to measure the expression levels of large numbers of genes simultaneously
