I have a lower-than-recommended concentration of DNA. Can I perform whole genome amplification (WGA) on my DNA prior to submitting it for SeqSNP?

Yes, there is no reason why a WGA method cannot be used to increase the DNA concentration of your sample. Please be aware that any PCR-based pre-amplification steps may introduce an element of bias and/or PCR errors within your target. Also, the DNA will most likely need a post-PCR clean-up step prior to submission.
