Preparation of Double-Stranded RNA for Drosophila RNA Interference (RNAi)

Leonie Misquitta, Qin Wei, and Bruce M. Paterson

This protocol was adapted from "Targeted Disruption of Gene Function in Drosophila by RNA Interference," Chapter 19, in Drosophila Protocols (eds. Sullivan et al.). Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, USA, 2000. Please note that this version of the protocol is a 2007 revision.


INTRODUCTION

RNA interference (RNAi) is a powerful method for determining the role of specific genes during Drosophila embryogenesis. It has been used in our laboratory to phenocopy a series of known mutations in Drosophila, including twist, engrailed, daughterless, Dmef2, and, to a lesser extent, white in the adult eye. This protocol describes the preparation of dsRNA by in vitro transcription of complementary strands of a cloned DNA fragment that codes for all or a portion of the gene of interest, followed by annealing of the transcribed RNA.
