Protocol uses Rnase protection to detect short interfering RNAs (siRNAs) in RNA preparations from Caenorhabditis elegans. SiRNAs can also be detected by northern blot. However, the Rnase protection assay seems to be more sensitive. - [Read Detection of siRNA in C. elegans Using Rnase Protection Protocol]
siRNAs produced upon the addition of dsRNA to Drosophila embryo extract are enriched in a micrococcus-nuclease-resistant fraction. After proteinase K treatment and dephosphorylation with calf intestinal phosphatase, these siRNAs mediate efficient RNAi in vitro. - [Read Preparation of siRNAs from Drosophila Embryo Extracts Protocol]
Short interfering RNAs (siRNAs) can be used to prime RNA synthesis by the RNA-dependent RNA polymerase (RdRP). SiRNAs can be used by RdRP as primers for specific cellular mRNAs, forming dsRNA products capable of inducing transitive RNAi. - [Read Protocol for siRNA-Primed RNA Synthesis Protocol]
Protocol describes a method for the delivery of siRNAs into mammalian cells in the absence of reporter plasmids. This is best achieved with transfection reagents developed for the delivery of antisense oligodeoxynucleotides. The quantities of reagents given below are calculated for the transfection of one well of a 24-well plate. - [Read Transfection of Mammalian Cells with siRNA Duplexes Protocol]
