Human Full ORF Lentiviral Expression Clones (ORFeomeV8.1)

The Human ORFeome V8.1 Lentiviral Library is a genome-scale collection of FULL ORF Expression Clones developed by researchers at Dana-Farber Cancer Institute and The Broad Institute. The main goal was to provide an extensive sequence-confirmed collection which enables both targeted experiments in, and large-scale screening of, mammalian cells. The collection comprises over 15,000 human ORFs in an expression-ready lentiviral system.

  • Ready-to-use Full ORF Expression Clones for gain-of-function studies
  • Lentiviral vector allows transduction of almost any mammalian cell type
  • CMV promoter drives strong protein expression
  • Blasticidin resistance for selection of transduced cells
  • Generation of fusion proteins with a V5 tag facilitating further applications
  • Fully sequenced & annotated clones
  • Extensive collection: over 12,700 ORFs covering ~11,000 human genes
