Food Contamination Testing Through Pulsed Field Gel Electrophoresis (PFGE) Systems Gaining Ground
Introduced in 1982 by Schwartz et al. Pulsed-field gel electrophoresis (PFGE) is a laboratory technique used by scientists to produce a DNA fingerprint for a bacterial isolate (a group of the same type of bacteria). By comparing the fingerprints of any two isolates, one can investigate if they belong to the same strain (i.e. the two isolates are clonal) or if they are genetically unrelated. PFGE is a powerful tool for characterizing various strains at the DNA level, obtaining relevant...
