Exploring whole genome amplification as a DNA recovery tool for molecular genetic studies.

ABSTRACT: The whole genome amplification (WGA) protocol evaluated during this study, GenomiPhi DNA amplification kit, is a novel method that is not based on polymerase chain reaction but rather relies on the highly processive and high fidelity Phi29 DNA polymerase to replicate linear genomic DNA by multiple strand displacement amplification. As little as 1 ng of genomic DNA template is sufficient to produce microgram quantities of high molecular weight DNA. The question explored during this study is whether such a WGA method is appropriate to reliably replenish and even recover depleted DNA samples that can be used for downstream genetic analysis. A series of human DNA samples was tested in our laboratory and validated using such analytical methods as gene-specific polymerase chain reaction, direct
