Abstract
The synthesis of single-stranded riboprobes or double-stranded RNAs for in situ hybridization and gene knockdowns often use vectors that require time-consuming plasmid restriction digests and inefficient gel purifications. Here, we present a faster protocol for the simultaneous plasmid restriction digestion and Gibson assembly of vectors for the synthesis of both riboprobes and double-stranded RNAs for in situ and RNA interference experiments, respectively. We illustrate the protocol with planaria in situ and RNAi assays, but it is applicable to any organism.
