The present invention relates to a method and a kit for detecting alleles of which the specificity and sensitivity in a DNA polymerase chain reaction (PCR), which is widely used for the detection of minor alleles such as single nucleotide polymorphisms or somatic mutations, are increased. More specifically, the present invention relates to a PCR-based method and kit for single nucleotide polymorphism (SNP) genotyping and somatic mutation detection, the method and kit adding a partially or fully double-stranded oligonucleotide for increasing discrimination to a PCR solution for selective amplification of alleles, so that PCR amplification is not affected when a primer 3′ terminal base is complementary (3′-matched) to a template but PCR amplification is strongly inhibited when a 3′ terminal base is not complementary (3′-mismatched).

Provided herein are methods and kits for detecting the presence of DNA and/or RNA mutations associated with cancer (e.g., lung cancer). The methods and kits employ microcarriers, each with a probe specific for a DNA or RNA mutation and an identifier unique to the probe sequence. Upon isolation and amplification of nucleic acids from a sample, hybridization of amplified DNA with a probe, specific for a DNA or RNA mutation, that is coupled to a microcarrier indicates the presence of the mutation in the sample. Since each microcarrier can be identified through detection of the identifier, multiplex screening assays are provided. Representative genes that can be screened for mutations include, e.g., KRAS, NRAS, PIK3CA, BRAF, EGFR, AKT1, MEK1, and HER2 for DNA mutations and/or ALK, ROS, RET, NTRK1, and cMET for RNA mutations.
