摘要:
The objective of this study was to apply the "on/off" switch consisting of 3′ phosphorothioate-modified allele specific primers and exo + polymerase in single base discrimination of A1555G and C1494T mutations in the highly conserved sites of the mitochondrial 12S rRNA. The two point mutations are the hotspot mutations associated with either aminoglycoside antibiotics induced deafness or inherited nonsyndromic hearing loss. The PCR products of mitochondrial DNA (mtDNA) 12S rRNA gene were inserted into the pMD19-T vector for transformation into...
