In a research paper published this month, scientists from the University of Missouri and molecular biology firm Lucigen have for the first time described a method to amplify DNA transformed into bacterial cells that contain the polymerase needed to drive the reaction.

The technique, dubbed ExCyto PCR, may be a useful tool to increase the throughput, efficiency, and cost of routine nucleic acid amplification, or "dirty PCR," because there is no need to add exogenous enzyme, the researchers said.
