mRNA Isolation with Dynabeads® in 15 minutes
Isolate the mRNA transcriptome in 15 minutes with Dynabeads® mRNA Direct Kits
15 minute mRNA isolation protocols are made possible by magnetic Dynabeads® coupled with Oligo(dT)25. Dynabeads® mRNA isolation beads specifically capture mRNA molecules from virtually any crude lysate. Magnetic bead handling and consistent results makes Dynabeads® mRNA Direct Kits the best choice for automated mRNA Isolation.
There is no need to isolate Total RNA when the desired molecule is mRNA
Only 1–5% of the Total RNA content of cells is actually mRNA. Dynabeads® mRNA purification kits and technologies target only the mRNA molecules and pull them directly out of solution. Compare this to Total RNA purification methods where up to 80% of the RNA yield is ribosomal RNA. Dynabeads® mRNA purification kits isolate the mRNA Transcriptome you need free of contaminating ribosomal RNA, tRNA, miRNA, siRNA, non-Poly-A RNA and pre-processed RNA.
Cited in over 5,000 publications
Dynabeads® mRNA purification methods have been proven to be extremely versatile, sensitive and consistently reliable. Dynabeads® mRNA Direct Kits capture just the transcriptome and are the preferred choice upstream of all applications that depend on the robust and sensitive isolation of extremely pure mRNA.
Whether you are isolating the mRNA Transcriptome for Next Generation Sequencing or simply interested in mRNA isolation for cDNA synthesis and cloning, the Dynabeads® mRNA Direct Kits give you a representative, ultra-pure and highly reproducible window into the mRNA Transcriptome.

How direct mRNA Isolation using Dynabeads® works
The method relies on A-T base pairing. Short sequences of oligo-dT are covalently bound to the surface of the Dynabeads® and will hybridize to the polyA tail of mRNA, allowing simple and rapid magnetic isolation (15 minutes). RNase inhibition together with stringent hybridization and washing steps ensure the isolation of pure, intact mRNA from crude samples, without the use of strong chaotropic agents.
The protocol is sensitive, flexible and can easily be scaled up or down to suit specific sample sizes, even down to single cells. This allows the detection of mRNA by RT-PCR from highly specialized cells. The isolated mRNA can be eluted in very small volumes and is suitable for use in all molecular biology applications. It is not necessary to elute the target off the beads since they do not interfere with downstream enzymatic reactions. The bead-bound oligo-dT can serve as a primer for reverse transcription and synthesis of first-strand cDNA, allowing direct RT-PCR and the construction of solid-phase cDNA libraries.
The inherent benefits of magnetic handling allow for easy washing, separation and concentration of bead-bound material without any need for centrifugation or columns. The lack of magnetic remanence combined with the excellent dispersion abilities also meet the demands required for automated systems and microfluidics.
These Dynabeads® are available as stand-alone beads and as part of mRNA isolation kits with buffers and solutions for easy mRNA transcriptome isolation.
