I then electrophrosed the same RNA samples on agarose gel to check its integrity. The agarose results showed that the RNA was contaminated with genomic DNA and that it was degraded to a certain level. To verify the results, I then proceeded to check these samples via the Agilent Bioanalyzer. However, the results generated by the bioanalyzer contradicted to the results produced by agarose gel. The bioanalyzer showed that the extracted RNA samples were free from any form of genomic DNA contamination. Also, the RIN value for some of the RNA samples was above 8.0.
