Suitable integrating vectors for use in the present invention include retrovirus vectors, lentivirus vectors transposon vectors, and adeno-associated virus vectors. Methods are provided in which the host cells are prepared by using the integrating vectors at a high multiplicity of infection. The host cells are useful for producing pharmaceutical proteins variants of proteins for use in screening assays and for direct use in high , throughput screening.

Why it's free to use

  • Filed June 29, 2001 and granted November 27, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 29, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 29, 2023.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
