Abstract

The NEBNext Ultra II FS DNA Module contains the enzymes and buffers required to convert a broad range of input amounts of intact DNA into fragmented DNA with 5´ phosphorylated 3´ dA-tailed ends. The module is optimized for use with the NEBNext Ultra II Ligation Module (NEB #E7595) and with the NEBNext Ultra II Q5 Master Mix (NEB #M0544) if amplification is required. The fast, user-friendly workflow has minimal hands on time.

Note: The Ultra II FS Module is not compatible with bisulfite conversion workflows

Each module component must pass rigorous control standards, and for each new lot the entire set of reagents is functionally validated together with NEB #E7595 and NEB #M0544 to construct indexed libraries that are sequenced on an Illumina sequencing platform.

For larger volume requirements, customized and bulk packaging is available by purchasing through OEM & Custom Solutions at NEB. Please contact custom@neb.com for further information.

Before start

Starting Material: 100 pg–500 ng purified, genomic DNA. We recommend that the DNA be in 1X TE (10 mM Tris pH 8.0, 1 mM EDTA), however, 10 mM Tris pH 7.5–8, low EDTA TE or H2O are also acceptable. If the input DNA is less than 26 µl, add TE (provided) to a final volume of 26 µl.

Steps

Fragmentation/End Prep

1.

Fragmentation occurs during the 37°C incubation step. Use the chart below to determine the incubation time required to generate the desired fragment sizes. Incubation time may need to be optimized for individual samples. See Figure 1 for a typical fragmentation pattern.

2.

Ensure that the Ultra II FS Reaction Buffer is completely thawed. If a precipitate is seen in the buffer, pipette up and down several times to break it up, and quickly vortex to mix. Place on ice until use.

3.

Vortex the Ultra II FS Enzyme Mix 5-8 seconds prior to use and place on ice.

Note
It is important to vortex the enzyme mix prior to use for optimal performance.

4.

Add the following components to a 0.2 ml thin wall PCR tube on ice:

AB
ComponentVolume per One Library
DNA26 µl
NEBNext Ultra II FS Reaction Buffer7 µl
NEBNext Ultra II FS Enzyme Mix2 µl
Total Volume35 µl
5.

Vortex the reaction for 0h 0m 5s and briefly spin in a microcentrifuge.

6.

In a thermocylcer, with the heated lid set to 75°C, run the following program:

5-30min @ 37°C

@ 0h 30m 0s @ 65°C

Hold @ 4°C

Note
Safe Stop Point: If necessary, samples can be stores at ; however, a slight loss in yield (~20%) may be observed. We recommend continuing with adaptor ligation using the NEBNext Ultra II Ligation Module (NEB #E7595) before stopping.
