A method for the cell-free synthesis and isolation of novel genes and polypeptides is provided. Within one embodiment an, expression unit is constructed onto which semi-random nucleotide sequences are attached. The semi-random nucleotide sequences are first transcribed to produce RNA and then translated under , conditions such that polysomes are produced. Polysomes which bind to a substance of interest are then isolated and disrupted; and the released mRNA is recovered. The mRNA is used to construct cDNA which is expressed to produce novel polypeptides.

Why it's free to use
- Filed October 4, 1990 and granted March 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
