GENERAL INFORMATION

///// Product Overview

The NEXTFLEX® Poly(A) Beads 2.0 are designed to isolate pure, intact messenger RNA (mRNA). The procedure includes two bead-based steps to ensure maximum removal of ribosomal RNA (rRNA) and non-messenger RNA contaminants. Magnetic based separation is used to retain poly(A) mRNA while removing all other transcripts. Beads are subsequently washed and mRNA is eluted. mRNA comprises approximately 1-5% of total RNA. For example, the maximum expected yield from 5 g is 250 ng poly(A) RNA. The following bead and total RNA ratios are suggested for optimal binding capacity and yield NEXTFLEX® Poly(A) Beads 2.0 are specifically designed and tested for RNA-seq applications. The NEXTFLEX® Poly(A) Beads 2.0 has been functionally-validated using the NEXTFLEX® Rapid Directional RNA-Seq Kit 2.0 and NEXTFLEX® RNA-Seq 2.0 UDI Barcodes. For additional product details, please email [email protected].

///// Kit Contents, Storage & Shelf Life

This kit contains enough material to extract mRNA from 8, 48, or 96 total RNA samples of 10 ng – 5 g total RNA for use with RNA-seq applications. The shelf life of all reagents is 12 months when stored properly. The NEXTFLEX® Poly(A) Elution Buffer 2.0, NEXTFLEX® Poly(A) Binding Buffer 2.0, NEXTFLEX® Poly(A) Washing Buffer 2.0, and NEXTFLEX® Poly(A) Beads 2.0 should be stored at 4°C.

///// Warnings & 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, you may contact your local distributor, or contact us at [email protected].

• Do not use the kit past the expiration date.
• Try to maintain a laboratory temperature of 20°­25°C (68°­77°F).
• RNA sample quality may vary between preparations. High quality RNA should have a 28S band that is twice as intense as the 18S band of ribosomal RNA.
• Vortex beads until they are a uniform suspension.
• Keep beads in liquid suspension during storage and handling. Never freeze the beads.
• Ensure beads pellet on magnet before removing clear supernatant. Completely remove all washing buffer before eluting mRNA.
• We recommend examining total RNA integrity using a LabChip® or equivalent.
• High quality total RNA preparations should have an RNA Integrity Number (RIN) or RNA Quality Score (RQS) greater than or equal to 7

///// Starting Materials

The NEXTFLEX® Poly(A) Beads 2.0 have been optimized and validated using 10 ng ­ 5 g of total RNA for RNA-seq applications. High quality total RNA preparations should have an RNA Integrity Number (RIN) 7. Alternatively, total RNA may be run on a 1­2% agarose gel and integrity examined by staining with ethidium bromide. High quality RNA should have a 28S band that is twice as intense as the 18S band of ribosomal RNA.

SAMPLE PREP PROTOCOL

Step A: NEXTFLEX® Poly(A) Bead Preparation Procedure

MATERIALS

• YELLOW CAP – NEXTFLEX® Poly (A) Beads 2.0
• YELLOW CAP or CLEAR CAP BOTTLE – NEXTFLEX® Poly (A) Binding Buffer 2.0

User Supplied

• Total RNA (10 ng ­ 5 g) in nuclease-free water
• 96-well PCR plate
• 96-well PCR plate magnetic stand
• Nuclease-free water as needed

This procedure takes approximately 10 minutes to complete and should be carried out before starting mRNA purification.

1. Thoroughly resuspend NEXTFLEX® Poly(A) Beads 2.0 by vertexing. Ensure no beads remain settled at the bottom of the bottle or tube.

2. Transfer 100 L of NEXTFLEX® Poly(A) Binding Buffer 2.0 to fresh wells of a new 96well PCR plate. Each sample requires its own well.

3. Add 20 L of NEXTFLEX® Poly(A) Bead 2.0 to each well and mix until homogenous. Each well must contain 100 L of NEXTFLEX® Poly(A) Binding Buffer 2.0 and 20
   L of NEXTFLEX® Poly(A) Beads 2.0.

4. Place the 96-well PCR plate on the magnet for 30 seconds or until solution becomes clear.

5. Discard the clear supernatant while the 96-well PCR plate remains on the magnet.

6. Remove 96-well PCR plate from magnet.

7. Resuspend pellet in 50 L of NEXTFLEX® Poly(A) Binding Buffer 2.0. Proceed to Step
   B: Purification of mRNA from total RNA.
