The method to internally label PCR products with multiple colored fluorescent dyes was developed and applied to multiple fluorescence-based PCR single-stranded conformational polymorphism (MF-PCR-SSCP) analysis. PCR-amplified fluorescent DNA fragments, which were internally labeled by adding fluorescent dUTPs ([F]dUTPs) to the PCR mixture, were heat-denatured and applied to a nondenaturing poly...
