Abstract, Conjugates in which a virus is bound via an antibody to a substance having an affinity for nucleic acid, for transporting gene constructs into higher eucaryotic cells. Complexes of the conjugates and nucleic acid are internalised in the cell possibly with, the co-operation of a cell-type-specific internalising factor, whilst the virus as part of the complex brings about the internalisation and the release of the contents of the endosomes, in which the complexes are located after entering the cell. Pharmaceutical preparations in which the nucleic acid is a therapeutically active gene construct, particularly for use in gene therapy, and transfection kits.

Why it's free to use
- Filed September 28, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 28, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 28, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
