Arrayed library
Arrayed Library
An Arrayed Library (pronounced: /əˈreɪd ˈlaɪbrəri/) is a collection of isolated DNA molecules that are stored in a regular array, such as in a grid pattern, on a solid support like a microtiter dish or a nylon membrane. The term "Arrayed Library" is derived from the English words "array" (meaning an ordered series or arrangement) and "library" (meaning a collection of materials).
History
The concept of an Arrayed Library was first introduced in the field of genomics in the late 20th century. It was developed as a method to systematically study the genome of various organisms.
Function
In an Arrayed Library, each well or spot on the array contains a unique DNA sequence from the organism's genome. This allows for the systematic study of the organism's genes. The Arrayed Library is often used in DNA sequencing, gene expression studies, and genetic screening.
Types
There are two main types of Arrayed Libraries: cDNA Libraries and Genomic Libraries. cDNA Libraries contain complementary DNA (cDNA) sequences, which are derived from the mRNA of the organism. Genomic Libraries contain DNA sequences from the entire genome of the organism.
