Abstract From the Canadian patent

Differentiation of Nucleic Acid Segments on the Basis of Nucleotide Differences, ABSTRACT, A process for distinguishing nucleic acid segments on the basis of nucleotide differences, thereby providing a rapid convenient means for detecting mutation is disclosed. The, present process comprises synthesizing separately complementary nucleic acid strands on each of at least two target nucleic acid templates using a nucleic acid polymerase and nucleoside triphosphate substrates, wherein at least one of the natural nucleoside triphosphate substrates is replaced with a mobility-shifting analog; denaturing the synthesized strands from the templates if necessary; and comparing the mobility of the …
