Description

Hieff NGS™ DNA Selection Beads are prepared based on the SPRI (Solid Phase Reverse Immobilization) principle and are applicable for DNA purification and size selection during the preparation of next-generation sequencing (NGS) libraries. Hieff NGS™ DNA Selection Beads are compatible with various DNA and RNA library prep kits.

  • DNA size selection

The calf thymus DNA was fragmented by sonication to prepare a fragment of 100-1,000 bp, and two rounds of size selection were performed according to Table 1. The results were analyzed using Agilent 2100 Bioanalyzer (Figure 1).

Table 1. Recommended condition for DNA size selection

Length of DNA fragment 250-350 bp 320-420 bp 450-550 bp 550-700 bp 700-900 bp 800-1,000 bp
Ratio of Beads: DNA for the 1st Round 0.80× 0.70× 0.60× 0.55× 0.50× 0.45×
Ratio of Beads: DNA for the 1st Round 0.20× 0.20× 0.20× 0.15× 0.15× 0.15×

Note: "×" in the table indicates the volume of sample DNA. For example, if the insert length of the library is 250 bp and the sample DNA volume is 100 μL, the volume of magnetic beads used in the first round of sorting is 0.80×100 μL=80 μL; the volume of magnetic beads used in the second round of sorting is 0.20× 100 μL=20 μL.
