The quality and purity of gDNA are tested by spectrophotometer and gel electrophoresis. The gDNA is provided ready to use for a variety of analyses including: SNP analysis, DNA methylation analysis, Southern Blotting, and PCR. The A260/A280 ratio of the genomic DNA is measured to be between the ranges of 1.7-1.9 using a Beckman Coulter DU 800 spectrophotometer
