The Thermo Scientific Trans-Lentiviral Packaging System utilizes the safest and most effective strategy for packaging virus to efficiently express your gene or shRNA of interest.  Co-transfection of the packaging plasmids and transfer vector into the packaging cell line, HEK293T, allows efficient production of lentiviral supernatant. The virus can then be transduced into a wide range of cell types, including both dividing and non-dividing mammalian cells (see Figure 1, Supporting Data).

The Trans-Lentiviral ORF Packaging Kit is designed for the optimal generation of highly efficient lentiviral particles containing ORF (Open Reading Frame) expression constructs. The produced viral particles can be used to transduce your cells or tissue of interest for the facilitation of robust gene knockdown.

Highlights

  • Consistent titers: 1 - 5 x 106 transducing units (TU) per mL are commonly achieved from unconcentrated packaging cell supernatant
  • Broad tropism: Effectively transduce most mammalian cell lines, including primary and non-dividing cells
  • Patented technology: Contains all genetic elements necessary to package both second and third generation lentiviral vectors

Highest Level of Biosafety

  • Five separate plasmids:  Genes required for packaging the viral genome are separated onto five plasmids to minimize the threat of recombinant, replication-competent virus production
  • Replication-incompetent:  None of the structural genes are actually present in the packaged viral genome, therefore no new replication-competent virus can be produced

Product Formats

  • With or without HEK293T cells
  • Starter kits (10 rxns) with an experimental control
  • Bulk sizes (50, 100 rxns) for large experiments
