Presence of Bacterial Phage-Like DNA Sequences in Commercial Taq DNA Polymerase Reagents

Abstract
Many studies have reported the presence of bacterial DNA contamination in commercial Taq DNA polymerase reagents. This is the first report of the presence of phage-like DNA sequences in certain commercial Taq DNA polymerase reagents. Precautions are needed when using amplification reagents with exogenous DNAs.
