title: A simple polymerase chain reaction apparatus based on a computer printer.
abstract: We describe a very simple laboratory-made polymerase chain reaction (PCR) apparatus. The reaction tubes are placed in a holder fixed through a mechanical arm to the tape cartridge of a computer printer. A computer controls the horizontal movement of the tube carrier by sending the proper printing commands. The holder is raised or lowered by a frame fixed to the paper-advancing roller of the printer. The system allows the programmed movement of the test tubes within the holder, successively through three thermal baths placed in front of the printer. DNA from single lambda gtll lysis plaques was successfully amplified with this system in our laboratory.
