Detection of rare K-ras codon 12 mutations using allele-specific competitive blocker PCR.

Abstract excerpt

Allele-specific competitive blocker PCR (ACB-PCR) is a sensitive allele-specific amplification method in which preferential amplification of the mutant allele occurs by using a primer that has more mismatches to the wild-type allele than to the mutant allele (mutant-specific primer, MSP). Additionally, a non-extendable primer with more mismatches to the mutant allele than to the wild-type allele (blocker primer,...
