Novel methods and compositions are provided for introducing a gene capable of modulating the genotype and phenotype into two or more tissues following systemic administration. The gene can be introduced into a mammalian host by way of an expression vector either as naked DNA or associated with lipid carriers particularly, cationic lipid carriers. Multiple individual tisssues can be transfected using naked DNA. Using a DNA: lipid carrier complex multiple tissues and cell types can be transfected. The techniques and compositions find use in the palliation or treatment of any of a variety of genetic-based disorders.

Why it's free to use
- Filed June 4, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 4, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 4, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
