A composition for treating a nucleic acid duplex wherein the composition is , capable of inhibiting denaturation of the duplex characterised in that the , composition comprises a ubiquitin-like protein and/or a macroglobulin. It has been found that ubiquitin-like proteins (e.g. ubiquitin NEDD8, RAD23 etc.) , and macroglobulins (e.g. .alpha.2-macroglobulin) are able to stabilise nucleic acid duplexes. A nucleic acid duplex which has been contacted with the composition of the invention can be subjected to more stringent processing conditions, with denaturation of the duplex being inhibited than would , otherwise be possible. Corresponding methods and uses are also provided.

Why it's free to use
- Filed December 11, 2002 and granted October 23, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 11, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 11, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
