Aptamers selected against cell surface receptors represent a unique set of ligands that can be used to target nanoparticles and other therapeutics to specific cell types. Here, we describe a method for using aptamers to deliver stable nucleic acid lipid particles (SNALPs) encapsulating small interfering RNA (siRNA) to cells in vitro. Using this method, we have demonstrated the ability of aptamer-conjugated SNALPs to achieve target-specific delivery and siRNA-mediated knockdown of a gene of interest. We also describe methods to characterize SNALP size, siRNA encapsulation efficiency, and aptamer conjugation efficiency.
