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 miniaturized, …

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.

2020年8月15日 · 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 - …

2022年8月8日 · DNA microarrays are solid supports, usually of glass or silicon, upon which DNA is attached in an organized, pre-determined grid fashion. Each spot of DNA, called a probe, represents …

2025年7月28日 · A microarray is a laboratory tool used to analyze many genes or proteins simultaneously. This technology involves placing thousands of microscopic spots of known DNA …

Two types of microarrays are gene expression microarray and tissue microarray (TMA). Techniques like Northern blot and reverse transcriptase-polymerase chain reaction (RT-PCR) allow testing for only a …

The term “microarray” broadly refers to a solid support such as a glass slide or silicon chip onto which many separate pools of molecules are attached in a regular pattern of microscopic spots in order to …

DNA microarrays are microscope slides that are printed with thousands of tiny spots in defined positions, with each spot containing a known DNA sequence or gene. Often, these slides are referred...

2024年12月19日 · Microarray experiments can indicate which genes are up- or down-regulated between samples from normal and diseased tissue, or two samples in the absence and presence of a certain …

A DNA microarray (also commonly known as a DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to simultaneously measure the …
