If you prefer to design your own siRNAs, you can choose siRNA target sites in a variety of different organisms based on the following guidelines. Reduce heat slowly to 75°C. the plant miRNA pathway is said to have evolved inde-pendentlyofthemetazoanone[5],thesecondarypre-miRNA structures appear to be similar when visually inspected on miRBase [6] which houses known pre-Previously, Ding et al. RNA interference (RNAi) is an extremely useful tool for inhibiting gene expression. General Design Guidelines.
