This invention relates to a system for introducing nucleic acid into the DNA of a cell. The system includes the use of a member of the SB family of transposases (SB) or nucleic acid encoding the transposase and a nucleic acid fragment that includes a nucleic acid sequence with flanking inverted repeats. The transposase recognizes at least a portion of an inverted repeats and incorporates the nucleic acid sequence into the DNA. Methods for use of this system are discussed.

Why it's free to use
- Filed March 11, 1998 and granted May 28, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 11, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
