The present invention relates to a quick and simple method for genetic testing,
particularly for SNP testing, using two kinds of primers which are complementary
to a mutant target and a wild-type target, respectively, and different in length
or migration speed in electrophoresis. These probes are allowed to hybridize with
targets, fluorophore-tagged nucleotides are attached to the primers, and electrophoresis
is carried out for discriminatory detection.
