Microarray - Wikipedia
A microarray is a multiplex lab-on-a-chip. [1] Its purpose is to simultaneously detect the expression of thousands of biological interactions. It is a two-dimensional array on a solid substrate —usually a glass slide or silicon thin-film cell —that assays (tests) large amounts of biological material using high-throughput screening ...

DNA microarray - Wikipedia
A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.

DNA Microarray Technology Fact Sheet - National Human Genome Research ...
The DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes. What is a DNA microarray? Scientists know that a mutation - or alteration - in a particular gene's DNA may contribute to a certain disease.

DNA Microarray- Definition, Principle, Procedure, Types - Microbe Notes
Principle of DNA Microarray Technique The principle of DNA microarrays lies on the hybridization between the nucleic acid strands. The property of complementary nucleic acid sequences is to specifically pair with each other by forming hydrogen bonds between complementary nucleotide base pairs.

Microarray Technology - National Human Genome Research Institute
Microarray technology is a general laboratory approach that involves binding an array of thousands to millions of known nucleic acid fragments to a solid surface, referred to as a “chip.” The chip is then bathed with DNA or RNA isolated from a study sample (such as cells or tissue).

DNA microarrays: Types, Applications and their future - PMC
The labeled cRNA or cDNA are then hybridized to the microarray, the array is washed and the signal is detected by measuring fluorescence at each spot. In the case of biotin labeled samples, the array is stained post-hybridization with fluorescently labeled streptavidin.

Microarray | Description, Fabrication, Analysis, Types, & Advantages ...
A microarray is a laboratory technique used in the study and analysis of biological molecules, particularly DNA and proteins, in which a probe of interest is affixed in a grid pattern to the surface of a small chip.

DNA Microarray- Definition, Principle, Steps, Types, Applications
DNA microarray technology (also known as DNA arrays, DNA chips, or biochips) is one of the most recent and significant advances in experimental molecular biology. Microarrays are laboratory instruments used to detect the expression of hundreds of genes at once and to identify the genes present in the genome of an organism.

microarray | Learn Science at Scitable - Nature
A microarray is a laboratory tool used to detect the expression of thousands of genes at the same time.

DNA microarrays: a powerful genomic tool for biomedical and clinical ...
In this publication we present the most common uses of DNA microarray technologies, provide an overview of their frequent biomedical applications, describe the steps of a typical laboratory procedure, guide the reader through the processing of a real experiment to detect differentially expressed genes, and list valuable web-based microarray ...
