Backbone manufacturerSharp Lab (http://web.mit.edu/sharplab/RNAi/Cloning.html)
Modifications to backbonepRL-TK (Promega) was digested with XbaI, and the following ligated in: ctagattccgagatatcggtaatgggcc This produced a modified vector, still containing an XbaI site, but now also containing an ApaI site, to allow for directional cloning of 3' UTR inserts. Final vector: TAATTctagattccgagatatcggtaatgggccCTAGA
