Amplified fragment length polymorphism

From Wikipedia, the free encyclopedia

Amplified fragment length polymorphism PCR, or "AFLP-PCR" (often AFLP), is a tool used in the study of genetics and in the practice of genetic engineering.

AFLP-PCR is a highly sensitive method for detecting polymorphisms in DNA.The technique was originally described by Vos and Zabeau in 1993. The procedure of this technique is divided into three steps:

  1. Digestion of total cellular DNA with one or more restriction enzymes and ligation of restriction half-site specific adaptors to all restriction fragments.
  2. Selective amplification of some of these fragments with two PCR primers that have corresponding adaptor and restriction site specific sequences.
  3. Electrophoretic separation of amplicons on a gel matrix, followed by visualisation of the band pattern.

A variation on AFLP is TE Display, used to detect transposable element mobility.
