NGS Fragment Kit (1-6000bp)

The NGS Fragment Kit (1-6000bp) (DNF-473) provides an automated solution to the quality assessment of high concentration NGS libraries prior to sequencing. The correct determination of molarity for optimum flow-cell loading is a critical step in NGS, and DNF-473 efficiently and accurately determines the average size of a library and its concentration. An accurate and precise molarity calculation helps ensure quality NGS results. Use DNF-473 to increase the efficiency of your genomic research.

Figure 1 depicts a typical separation of the Standard Sensitivity NGS DNA Ladder (DNF-374). The peaks are well separated and clearly defined, providing a standard curve for the sizing and quantification of DNA smears, namely NGS libraries.

An example of a high quality NGS library is depicted in Figure 2. Signs of a successful library preparation include:

  • A smooth, defined smear of the desired average size
  • No Primer Dimers
  • No Adapter Dimers

Conversely, a poor quality separation is stipulated by the lack of one or more of the characteristics of a high quality NGS smear. An NGS library of poor quality is more likely to compromise sequencing results, decreasing depth and providing lower quality reads.
