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 Zabeau & Vos in 1993. The procedure of this technique is divided into three steps:
- Digestion of total cellular DNA with one or more restriction enzymes and ligation of restriction half-site specific adaptors to all restriction fragments.
- Selective amplification of some of these fragments with two PCR primers that have corresponding adaptor and restriction site specific sequences.
- 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.
