HS Genomic DNA 50kb Kit

The HS Genomic DNA 50kb Kit (DNF-468) is ideal for the automated quality assessment of gDNA for downstream applications such as next generation sequencing. A broad sizing range allows researchers to accurately size gDNA samples through 60 Kb. Perfect for precious or low concentration samples, use only 2 µL of sample and quantify samples with concentrations as low as 0.3 ng/µL.

The accurate sizing and quantification of genomic DNA necessitates the use of a high-quality DNA ladder. The HS Genomic DNA 50kb Kit employs the High Sensitivity Extended Genomic DNA Ladder (Figure 1) to reliably size and quantify gDNA samples. Sizing through 60 Kb is achieved through the inclusion of a 48.5 Kb DNA fragment. Reliable and accurate quantification of genomic DNA is achieved using carefully calibrated ladder fragment concentrations.

Pure, high-quality genomic DNA is necessary for many applications from PCR to NGS. The quality assessment of genomic DNA is often dependent on subjective criteria and the interpretation of the researcher. Post-separation analysis in PROSize® Data Analysis Software alleviates these issues with clear depictions of separations in two formats – digital gel image and electropherogram (Figure 2) – and the use of a dynamic quality metric, the Genomic Quality Number (GQN). Specially designed for the changing demands of genomic DNA QC analysis, the GQN employs a user-defined size threshold. The GQN is reported as a value between 0 and 10, with high values corresponding to more of the gDNA sample falling above the user-selected size threshold. An example of the GQN is shown in Figure 2. In the example, a size threshold of 10,000 bp (shown as a dotted blue line) was selected, producing a GQN of 9.0.

Capillary electrophoresis was performed with a Fragment Analyzer equipped with a Short Capillary Array (33-55) using the HS Genomic DNA 50kb Kit (DNF-468). The Peak Table, shown inset into the electropherogram, provides crucial information including: concentration, size threshold, and GQN.

For many applications, it is crucial to know the concentration of genomic DNA. The HS Genomic DNA 50kb Kit provides confident assessments of sample concentration. When compared to a fluorometric method of quantification, the Fragment Analyzer using the HS Genomic DNA 50kb Kit provides the same concentration values (Figure 3).
