Reliable design of these molecules is essential for the needs of large functional genomics projects. 2016, 63, 71–77. RNAi approaches, including microRNA (miRNA) regulatory pathway, offer great tools for functional characterization of unknown genes. 1 Identification of miRNA binding sites. Knowledgebase update and creation Knowledgebase for network creation. sRNAPrimerDB allows users to design several types of primers including generic or specific reverse. Conclusion. PCR (2 primers) qPCR (2 primers + probe; for use in 5′ nuclease assays) qPCR (2 primers; for use with intercalating dyes) RNA interference (RNAi) is an extremely useful tool for inhibiting gene expression. RNAi is a specific, potent, and highly successful approach for loss-of-function studies in virtually all eukaryotic organisms. The tool designs the miRNA specific sequence of the stem-loop RT primer as well. The dsRNA can be delivered as an siRNA (short interfering RNA) via transfection, or shRNA (short hairpin.
