    Abstract:
    The polymerase chain reaction (PCR) is a technique for rapid amplification of target DNA sequences. During the past several years, a large number of research applications of PCR have appeared, many of which may prove to be useful clinically. We report the use of capillary electrophoresis, a fully automated technique, as an alternative to polyacrylamide gel electrophoresis for the detection of PCR-amplified viral and cellular DNA. We describe conditions for rapid separation, detection, and discrimination of PCR products from the human immunodeficiency virus type 1 gag gene and the HLA-DQ-alpha gene amplified from the human immunodeficiency virus provirus-containing U1.1 cell line. The sensitivity achieved with the use of capillary electrophoresis analysis was roughly equivalent to that of ethidium bromide staining of polyacrylamide gel electrophoresis gels. Further refinement of capillary electrophoresis for automated detection and quantitation of PCR-amplified products should expedite more widespread application of PCR analysis in the clinical laboratory.
