The Total RNA Isolation Kit provides a fast, simple, and cost-effective method for the isolation of total RNA from the whole blood, mammalian cells, and bacterial cells. Detergents and chaotropic salt are used to lyse cells and inactivate RNase. The specialized high-salt buffering system allows RNA species bases to bind to the glass fiber matrix of the spin column while contaminants pass through the column. Impurities are efficiently washed away, and the pure RNA is eluted with the REL Buffer without phenol extraction or alcohol precipitation. The RNA purified with the Total RNA Isolation Kit is suitable for a variety of routine applications, including the RT-PCR, cDNA Synthesis, Northern Blotting, Differential display, Primer Extension and mRNA selection. The entire procedure can be completed within 25-40 minutes.

  • Sample:
  • Up to 300 μl of whole bloodUp to 107 mammalian cells

Refer to the table below to troubleshoot problems that you may encounter when purifying total RNA.

Degraded RNA/ low integrityRNases contaminantClean everything, use barrier tips, wear gloves and a lab coat, and use RNase-free enzymes, EX: RNase inhibitor.
Low yields of RNAIncomplete lysis and homogenizationUse the appropriate method for the lysate preparation based on the amount of the starting materials immersed in the Buffer RA to achieve the optimal lysis.
Incorrect elution conditionsAdd 50 μl of the RE Buffer to the center of each Column DR, let it stand for 2 minutes, and centrifuge at 14,000 x g for 2 minutes.
Inhibition of downstream enzymatic reactionsPresence of ethanol in the purified RNARepeat the wash step: Centrifuge at 14,000 x g again for 2 minutes to remove the residual W2 Buffer.
  • During the operation, always wear the latex or vinyl gloves while handling reagents and RNA samples to prevent the RNase contamination.
  • Add 60 ml of the ethanol (96~100%) to the Buffer W2, and shake before use (see bottle label for volume).
  • Check Buffers before use for salt precipitation. Re-dissolve any precipitate by warming up to 37°C.
  • The Buffers RA and W1 contain irritants., so please wear gloves when handling these buffers.
  • Research Use Only. Not intended for any animal or human therapeutic or diagnostic uses.
