PCR and CE for Fruit Analysis

Researchers from the Bio-Molecular Innovation Team of LGC (UK) used polymerase chain reaction (PCR) and Agilent’s DNA 1000 chip and model 2100 capillary electrophoresis (CE) system to analyze raspberry and strawberry DNA. The goal of the study was to differentiate between DNA from the two fruits by analyzing microsatellite markers. The researchers were able to find sufficient differences between the strawberry and raspberry DNA samples to show the technique’s potential for future food authentication studies.
