Product Overview

The NEXTFLEX® Rapid XP V2 DNA-Seq kit is designed for ~4 hours library construction and pooling from 100 pg – 1 µg of DNA. The kit can be used to prepare single, paired-end, and multiplexed DNA libraries for sequencing using Illumina® platforms. The NEXTFLEX® 1-step Fragmentation, End-Repair, and Adenylation simplifies workflow and shortens hands-on library construction time. In addition, the availability of up to 1,536 different Unique Dual Index adapter barcodes facilitates high-throughput applications.

There are three main steps involved in preparing DNA for sequencing: DNA fragmentation/end repair/ adenylation, adapter ligation, and post-adapter ligation PCR amplification. The NEXTFLEX® Rapid XP V2 DNA-Seq kit contains the necessary material to take the user’s extracted nucleic acid sample through preparation and amplification for loading onto flow cells for sequencing

Kit Contents, Storage & Shelf Life

The NEXTFLEX® Rapid XP V2 DNA-Seq kit contains enough material to prepare 8, 48 or 96 samples for Illumina® sequencing. The shelf-life of all reagents is at least 6 months when stored properly. The Nuclease-free Water and, Elution Buffer can be stored at room temperature. The NEXTFLEX® Cleanup Beads XP and NEXTFLEX® Normalization Beads V2 should be stored at 4°C, and all other components should be stored at -20°C.

Warnings and Precautions

We strongly recommend that you read the following warnings and precautions. Periodically, optimizations and revisions are made to the components and manual. Therefore, it is important to follow the protocol included with the kit. If you need further assistance, contact us at [email protected].

Do not use the kit past the expiration date.
Ensure pipettes are properly calibrated as library preparations are highly sensitive to pipetting error.
Do not remove enzymes from -20ºC until immediately before use; return to -20ºC immediately after use.
This kit does not contain Barcoded Adapter. To enable multiplexing, please use the appropriate concentration of the NEXTFLEX® barcoded adapters during the Adapter Ligation step.
Do not freeze NEXTFLEX® Cleanup Beads XP or NEXTFLEX® Normalization Beads V2.
Vortex beads until they are a uniform suspension.
Thermal cycling should be performed with a heated lid (103ºC-105ºC) except where specified.
Maintain a laboratory temperature of 20º–25ºC (68º–77ºF).
DNA sample quality may vary between preparations. It is the user’s responsibility to utilize high quality DNA. DNA that is heavily nicked or damaged may cause library preparation failure. Absorbance measurements at 260 nm are commonly used to quantify DNA and 260 nm / 280 nm ratios of 1.8 – 2.0 usually indicate relatively pure DNA. The user should be aware that contaminating RNA, nucleotides and single-stranded DNA may affect the amount of usable DNA in a sample preparation.
Presence of EDTA in starting input DNA can alter final library size. For optimal results, input DNA should be resuspended in ultrapure water or low TE buffer.

Starting Material

The NEXTFLEX® Rapid XP V2 DNA-Seq kit has been optimized and validated using high quality genomic DNA inputs ranging from 100 pg – 1 µg.

Reagent Preparation

Briefly spin down each component to ensure material has not lodged in the cap or side of tube. Keep on ice and vortex each NEXTFLEX® component except the NEXTFLEX® Fragmentation Enzyme Mix just prior to use. Nuclease-free Water and Elution Buffer should be stored at room temperature. NEXTFLEX® Cleanup Beads XP and NEXTFLEX® Normalization Beads V2 should be stored at 4°C but equilibrated to room temperature prior to use.
DTT in buffers may precipitate after freezing. If precipitate is seen, vortex buffer for 1-2 minutes or until the precipitate is in solution. The performance of the buffer is not affected once the precipitate is in solution.
The 80% ethanol for bead washing steps should be freshly made prior to use.
Allow NEXTFLEX® Cleanup Beads XP to come to room temperature and vortex the beads until homogenous.
NEXTFLEX® Normalization Beads V2 preparation.
NOTE: NEXTFLEX® Normalization Beads V2 should be made for immediate use. Once 100% EtOH has been added to NEXTFLEX® Normalization Beads V2, they should be used within 2 weeks.

The following table lists the recommended incubation times as a guideline for fragmentation.

The mode fragment size can be adjusted by changing the duration of incubation at this 35 °C step. These times are recommendations only, and incubation time may need to be optimized for different sample inputs and types to obtain desired mode fragment size.

Input DNA (ng)	Fragmentation Time (min) at 35°C
