Large double copy vectors are functional but show a size-dependent decline in transduction efficiency. Vrije Universiteit Brussel
The development of SIN-lentivectors has paved the way for the double copy vectors (DCV), which substitute the deletion in the 3'LTR with either transgenic or insulator sequences. However, the limits of this approach remain unclear. Previous results have demonstrated that transduction efficiencies of DCV carrying large insulator inserts in their 3'LTRs were impaired in a size-dependent manner. We wondered if this was also true for ...
