Preparation of Cells in 96-Well Plates for siRNA Transfection and High-Content Analysis

INTRODUCTIONRNA interference using siRNA libraries is a powerful technology for elucidating gene function by downregulating gene expression at the post-transcriptional level. Phenotypic changes associated with siRNA knockdown can be monitored using cell lines expressing fluorescent reporter proteins. Test siRNAs are transiently transfected into the reporter cell line and behavior of the fluorescent reporter probe is monitored using a high-content imaging system. A range of cell features and additional fluorescent probes can be monitored to assess the effects of knockdown. This article details how to perform siRNA transfection in multiwell plates for subsequent high-content analysis.
