Minivector DNA construction. Minivector DNA for expression of shRNA against GFP and ALK were generated using the λ-integrase (Int) site-specific recombination system as described in Fogg et al.19 shRNA sequences were cloned into the parent plasmid (far left); the three parent plasmids (pMV) and Minivector (mv) DNAs used in this study are identified.
