How can I check DNA sample quality before using the Somatic Mutation PCR Arrays & Assays?

We recommend using the QIAGEN QIAamp DNA Mini Kit for DNA isolation, with the recommended RNase step. For sample quality, we recommend assaying for DNA concentration & purity with a UV Spectrophotometer; for DNA Integrity, an agarose gel should be run; and DNA quality and consistency can be checked on the Somatic Mutations QC plate that measures 7 reference genes by RT-PCR.
