Identification of Microorganisms Using Random Primed PCR

摘要

The polymerase chain reaction has facilitated the use of molecular approaches in microbiology including new strategies for the rapid identification of micro-organisms. Approaches based on the use of random primers and standard conditions, allows characteristic DNA fingerprints to be generated from any micro-organism even in the absence of information about its DNA sequence. Different primers can be used to produce genus-specific, species-specific, or even strain-specific DNA fingerprints. This article covers the background to this strategy, describes three different approaches to generating DNA fingerprints using random primers, and provides experimental detail for one method, RAPD.
