    摘要: The present invention includes a method of allele-specific amplification, utilizing an allele-specific oligonucleotide, at least partially complementary to more than one variant of the target sequence, having a 3'-terminal nucleotide complementary to only one variant of the target sequence and having at least one nucleotide with a base covalently modified at the exocyclic amino group, wherein the allele-specific oligonucleotide is extended by a nucleotide-incorporating biocatalyst predominantly when hybridized to the variant of the target sequence for which it has said complementary 3'-terminal nucleotide.
