A step-by-step procedure to analyze the efficacy of siRNA using real-time PCR.
Knockdown of cellular RNA using short interfering RNA has enabled researchers to perform loss-of-function (LOF) experiments in a wide variety of cell types and model systems. RNA interference techniques and reagents have made possible experiments that test everything from the analysis of function of single genes to screening for genes that are involved in critical biological pathways on a genome-wide scale. Although siRNA experiments are generally common practice in research laboratories, it is still important to keep in mind that many factors can influence efficacy of knockdown. A properly designed siRNA, optimized protocols of siRNA delivery, and an appropriate and well-optimized readout are all critical parameters for ensuring the success of your experiment. In this chapter, we provide step-by-step procedures for performing an siRNA knockdown experiment from cell culture to analysis of knockdown using quantitative real-time PCR.
