This is the recommended vector for cloning and expressing new shRNA sequences. This plasmid is being used by The RNAi Consortium to produce their shRNA library http://www.broad.mit.edu/genome_bio/trc/ The 1.9kb stuffer can be released with AgeI and EcoRI and replaced with your shRNA sequence of choice.
