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- Definition, Principle, Procedure, Types
Aug 8, 2022 · 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 a single gene. DNA microarrays can analyze the expression of tens of thousands of genes simultaneously.
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 ...
