Popis: | Heteroduplex formation, required for the complete detection of hemi/homozygotes using high-resolution melting analysis, can be induced either by pre-PCR mixing of genomic DNAs or by post-PCR mixing of PCR products from unknown and reference samples. This study investigates the effects of both methods using two single nucleotide polymorphisms in X-linked DMD gene. The results show that both methods resulted in the same effect when mixing samples with the same gene copy number. Mixing samples with different gene copy numbers has not been previously explored and we show that post-PCR mixing is insensitive to gene copy number differences as compared to pre-PCR mixing. |
