Fast cloning inverted repeats for RNA interference.

ABSTRACT: Double-stranded RNA (dsRNA) can induce post-transcriptional gene silencing in a wide variety of organisms. Commonly, inverted repeats are used to produce dsRNA to silence genes of interest. However, cloning inverted repeats still remains a rate-limiting step for widely applying this technique. Here we describe a pGEM-T-based vector, pGEM-WIZ, designed to produce inverted repeats for any Drosophila gene. pGEM-WIZ has a high efficiency in assembling inverted repeats and the repeats in this vector are stable in regular Escherichia coli strains. Furthermore, we have developed a method for rapid selection of clones with an inverted repeat based on size and relative copy number of the vector with or without an insert. This method further eases the cloning process. The inverted repeat cassette as
