Luco Viral RNA Extraction

DNA and RNA purification

DNA and RNA extraction is a basic method used in molecular biology. The need for high-quality, highly pure nucleic acid is important for a wide range of research and clinical applications. Nucleic acid purification is an initial step in many molecular biology and genomics workflows.

DNA and RNA samples are often obtained from crude preparations. Genomic DNA, plasmid DNA, and total RNA can be extracted and purified from a variety of sources, including bacterial and mammalian cells, plant tissue, fungal tissue, mammalian tissue, blood, plasma, serum, viruses, buccal swabs, nasals, gel matrices, PCRs, and other enzymatic reactions. Isolation of nucleic acid from these samples often involves lysis of cell membranes or homogenization of the sample, followed by removal of proteins, enzymes, detergents, salts, and lipids.

Common approaches include:

  • alkaline extraction
  • Phenol-chloroform extraction
  • Density gradient centrifugation with caesium chloride (CsCl)
  • Oligo(dT)-cellulose chromatography
  • silica matrix
  • glass beads
  • Diatomaceous earth
  • Anion exchange chromatography
  • Size exclusion chromatography

The final application will dictate the best purification method. Downstream applications include PCR, qPCR, restriction digests, ligation, cloning, genotyping, gene expression analysis, next-generation sequencing (NGS), and Northern and Southern blotting.

Total RNA Extraction Kit

The E.Z.N.A.® Total RNA Kit I provides a simple and rapid method for the isolation of up to 100 µg of total RNA from cultured eukaryotic cells and soft tissues. Multiple samples of up to 1 x 107 eukaryotic cells or 30 mg of tissue can be processed in parallel in less than 20 minutes. The purified RNA can be used in many downstream applications, such as RT-PCR, Northern blotting, nuclease protection assay, and in vitro translation.
