The error rate during amplification has not been determined, but without proofreading, the whole genome amplification polymerase error rate is expected to be similar to native Taq polymerase, typically in the range of approximately 1 × 10^5 to 2 × 10^4. Publications specifically quantifying coverage can be found in early work with WGA4, which reported an overall measured coverage of 78% for aneuploidy screening (doi.org/10.1016/j.fertnstert.2007.07.789). Later work using WGA4 to measure gene copy number variation (https://doi.org/10.1038/srep11415) showed coverage varied by GC content; in areas with a GC composition of 30-60%, the coverage varied approximately 60-120% (rat genomic DNA has 41.9% GC). Several papers have been published on obtaining optimal results and accurate analysis from the kit, with the most relevant being (https://doi.org/10.1038/nprot.2012.039).

Is there an estimate for the ratio of ssDNA to dsDNA, like roughly 3 times more ssDNA than dsDNA? Also, does the advertised 5-10 ug of DNA for WGA4 correspond to total DNA or just dsDNA?
1 answer-
The ratio of ssDNA to dsDNA has not been determined. However, the 5-10 ug of DNA advertised for WGA4 corresponds to total DNA, not just dsDNA.

What A260/A280 ratios are expected for a successful WGA 4 product using the WGA4 kit?
1 answer-
The A260/280 has not been measured for any amplification product; however, given that starting material is infinitesimal quantities and adding very little protein, the expectation is for A260/280 to resemble that of pure DNA, especially after purification using the GenElute PCR Cleanup Kit (Catalog Number NA1020).

Can Product WGA4, GenomePlex® Single Cell Whole Genome Amplification Kit, be used with purified DNA?
1 answer-
Yes. The kit is designed to amplify the small amount of DNA that is present in a single cell (3-5 pg). It will also work with small amounts of purified DNA; we recommend less than 100 pg.
