For the development of a novel SNP typing method using BDF (base-discriminating fluorescent) nucleosides in biological samples, we examined the detection of the single base alteration in BRCA1 gene with PCR products amplified by an asymmetric PCR. A combination of PyU- and PyC-containing BDF probes clearly facilitates the discrimination of not only A/G homozygous samples but also heterozygous samples. The present SNP typing method with BDF probes is a very powerful homogeneous assay that does not require a special device or time-consuming steps.
