In this paper, we propose a new evaluation method using external standard RNA for quality control of the extracted RNA. RNA Integrity Number and UV absorption are generally used as a basis for RNA quality control; however, these methods do not always reflect the quality of mRNA. While standard RNA is supposedly designed on the basis of mRNA, it has the potential to be used to evaluate the quality of the mRNA. In this study, we took into consideration the three essential factors, viz., yield of mRNA, inhibition to DNA polymerase, and degradation of mRNA for determining the RNA quality using standard RNA. It would be possible to know yield of mRNA and inhibition of the enzyme reaction by adding standard RNA before RNA extraction and looking at standard RNA loss. Degradation was evaluated by comparing the differences in the 3’ and 5’ regions of the RNA. In our study, it was demonstrated that in the crude extract of Saccharomyces cerevisiae, degradation was comparatively higher at the 3’ end of RNA than at the 5’ end. Hence, the degree of RNA degradation can be evaluated by comparing the ratio of degradation from the 3’ and 5’ end.
