Ease of performance, qualitative accuracy, and quantitative fidelity of different WGA methods, such as degenerate oligonucleotide-primed polymerase chain reaction (DOP-PCR), ligation-mediated PCR (LM-PCR) and strand displacement amplification (SDA), were compared in amplifyinggenomic DNA derived from karyotype-confirmed amniocytes and the cancer cell line SAOS2.
Using analysis with microsatellite markers, single nucleotide polymorphism markers, and array-CGH, our results suggested that: (1) genomic DNA amplified from DOP-PCR resulted in false positive and negative results by analysis with array-CGH; (2) SDA is the easiest performance method among the three WGA methods; and (3) amplified DNA products generated by LM-PCR best reflect the original genomic DNA.
The amplified DNA products generated by LM-PCR best reflect the original genomic DNA.
