Description

New! The only commercially available kit dedicated to secondary RNA purification.

The PowerClean® Pro RNA Clean-Up Kit utilizes our patented Inhibitor Removal Technology® (IRT) to provide researchers with a novel and proprietary method for cleaning up previously isolated RNA. Starting RNA may be amber to brown in appearance; an indicator of PCR inhibiting substances, particularly humics and polyphenols.  Even samples that appear colorless may contain PCR inhibitors which can be cleaned up with this kit. The PowerClean® Pro RNA Clean-Up Kit will remove this brown color as well as any PCR inhibiting substances, such as heme, polysaccharides, polyphenols fulvic acids and dyes.  A high purity of RNA is achieved allowing for more successful RT-PCR amplification of RNA derived from organisms in the original sample. This kit was validated with RNA isolated from a variety of problematic soils and also with RNA samples spiked with commercial humic acids.  However, it performs well on RNA isolated from virtually any sample source. 

Archived or previously isolated RNA samples are purified when combined with our proprietary RNA Clean-Up reagents. Inhibitors are selectively removed from the RNA solution. All RNA is captured on a silica membrane in a spin column format.  RNA is then washed and eluted from the membrane. Percentage recovery varies depending on the level of inhibitors that may be influencing the RNA yield measurement. Purified RNA is ready for RT-PCR analysis and other downstream applications.

Figure 1. Elimination of humic acids from RNA. The amount, quality and molecular weight of RNA visualized on the gel was similar for the starting sample and the samples following clean up (A). The starting sample contained humic acids, which absorb at A230-320. Following clean-up, the 260/280 and 260/230 ratios increased to levels consistent with pure RNA and the concentration of the RNA decreased to an average of 129.93 ng/μl, a value that was confirmed by quantitation using a Qubit PicoGreen Assay (data not shown). The decrease in concentration is due to removal of humic acids, which falsely inflate the concentration due to their absorbance at A230-320. More information about the effect of inhibitors on RNA concentration can be found in our tech tip article.

Figure 2. Successful RT-qPCR. RNA described in Fig. 1 was examined via RT-qPCR with a Bacillus 16S assay (1l of undiluted RNA or a 1:10 dilution). Samples were free of inhibitors, as indicated by successful amplification of the undiluted RNA and a difference of approximately 3 cycles between the undiluted and the 1:10 dilution. Starting samples and 1:10 dilutions failed to amplify due to the presence of inhibitors.
