◊In RACE (Rapid Amplification of cDNA Ends) by the single-primer method* of this kit, the targeted cDNA is amplified by PCR with only a gene-specific primer using ds cDNA as a template.
◊The mechanism is based on that the terminal region of the ds cDNA is partially denatured at 68 C for the extension reaction and that the linear DNA molecule tends to circularize.
◊Upon reaching the 5’ end of the template DNA, thermostable DNA polymerase switches templates to the 5' terminal region of the newly synthesized daughter strand at a certain probability and synthesizes DNA sequences complementary to the gene-specific primer.
◊Using this daughter strand as a template, the targeted cDNA is amplified with only a gene- specific primer.
