This study shows that the accuracy of the quantification of genomic DNA by the commonly used Hoechst- and PicoGreen-based assays is drastically affected by its degree of fragmentation. Specifically, it was shown that these assays underestimate by 70% the concentration of double-stranded DNA (dsDNA) with sizes less than 23 kb. On the other hand, DNA sizes greater and less than approximately 23 kb are commonly characterized as intact and fragmented genomic DNA, respectively, by the agarose… CONTINUE READING
