We have enhanced the polymerase chain reaction (PCR) such that specific DNA sequences can be detected without opening the reaction tube. This enhancement requires the addition of ethidium bromide (EtBr) to a PCR. Since the fluorescence of EtBr increases in the presence of double–stranded (ds) DNA an increase in fluorescence in such a PCR indicates a positive amplification, which can be easily monitored externally. In fact, amplification can be continuously monitored in order to follow its… Expand

    The novel One-PCR-tube method is competitive for commercial kits with the same time and simpler operation procedure, and may be widely used for identifying food that contains modified DNA and specific pathogens in the field. Expand
    Quantitative PCR Technology
    Higuchi et al. (1992, 1993) pioneered the analysis of PCR kinetics by constructing a system that detects PCR products as they accumulate. This “real-time” system includes the intercalator ethidiumExpand
    A homogeneous fluorescence assay for PCR amplicons: its application to real-time, single-tube genotyping.
    TLDR
    Three-STAR is a universal system that can either use a single probe for the detection of any one target DNA sequence or a single pair of probes for genotyping any bi-allelic polymorphism and is particularly useful for the single-tube genotype analysis of a variety of human DNA polymorphisms and mutations.

    Kinetic PCR analysis using a CCD camera and without using oligonucleotide probes
    TLDR
    This chapter discusses the various approaches to monitor the PCR amplifications including cycle-by-cycle monitoring and empathizes on the use of a charged-coupled device (CCD) camera, which is a simpler, less expensive method of monitoring multiple PCRs. Expand
