Isolate the Complete mRNA Transcriptome in 15 minutes. This mRNA isolation kit specifically targets and captures mRNA molecules from virtually any crude sample and eliminates the need to purify total RNA when the desired information bearing nucleic acid is mRNA. Since the mRNA content of cellular total RNA is only ~1-5%, why isolate total RNA when just a sub-fraction of the total RNA component is mRNA? Other technologies designed to purify total RNA yield ~80% ribosomal RNA and force mRNA to compete with ribosomal RNA, transfer RNA, micro RNA, small nucleolar RNA and small cytoplasmic RNA for membrane binding.
15 minute procedure yields pure intact mRNA
Extremely pure mRNA isolation, best choice upstream of cDNA synthesis
Exquisitely sensitive mRNA isolation enables cDNA synthesis and cDNA library construction from ultra-small starting samples. (Enables cDNA library construction from a single cell.)
The mRNA purification beads in the 查看更多Dynabeads® mRNA DIRECT™ Kit specifically target and capture the mRNA transcriptome from an extremely wide variety of crude starting samples. Ribosomal RNA, DNA, proteins, and small RNA molecules (such as transfer RNA, micro RNA and small nucleolar RNA) do not bind to the beads and are discarded. Only polyadenylated RNA species (mRNA) are captured. Isolated mRNA is pure, eliminating the need for ribosomal RNA subtraction or a post-extraction DNase treatment.
RNase inhibitior agents in the Lysis/Binding buffer together with stringent hybridization and washing steps ensure that the mRNA isolation yields intact mRNA even from samples that are rich in RNA degrading enzymes. Careful buffer formulations prevent RNA degradation without the use of strong chaotropic agents.
