It is possible that some cell lines have lost the ability to perform RNAi or that cells derived from certain tissues do not support RNAi. This reporter assay, for RNAi in mammalian cells, can be used to establish whether the cells under study are susceptible to RNAi. - [Read Cotransfection of Luciferase Reporter Plasmids with siRNA Duplexes Protocol]
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]
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]
To target a specific mRNA for degradation, a portion of the mRNA target sequence must be known, and a segment of the target mRNA must be chosen that will be used for targeting by the cognate siRNA duplex. Protocol describes the selection of siRNA sequences for mammalian RNAi. - [Read Selection of siRNA Sequences for Mammalian RNAi Protocol]
Protocol Involves the transfection of siRNA into RAW 264. 7 cells using Lipofectamine 2000. Cells are transfected with siRNA twice (on subsequent days). Target gene knockdown is assessed from total RNA isolated 48 hr post-transfection or from protein isolated 72 hr post-transfection. - [Read siRNA Double Transfection of RAW 264.7 Cells with Lipofectamine 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]
