The post-meiotic regulatory region may be transition protein 1 promoter. The selection sequence may be a direct or indirect mediator or a , detectable marker.

Why it's free to use
- Filed November 9, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 9, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
