A method for the selection of one or more desired polypeptides includes cell free expression of nucleic acid molecules immobilized on a solid support system to produce polypeptides. The solid support carrying system is for biospecific interaction with at least the desired polypeptide or a molecule attached thereto. The method also includes separation of the solid support carrying both the desired polypeptide and the nucleic acid encoding it. Finally, the method optionally includes recovery of the nucleic acid and/or the desired polypeptide, and molecular libraries for use in these methods.

In vitro selection and optional identification of polypeptides using solid support carriers

The present invention provides a method of identifying a base at a target position in a single-stranded sample DNA sequence wherein an extension primer, which hybridizes to the sample DNA immediately adjacent to the target position, is provided and the sample DNA and extension primer are subjected to a polymerization reaction in the presence of a deoxynucleotide or dideoxynucleotide, whereby the deoxynucleotide or dideoxynucleotide will only become incorporated and release pyrophosphate if it is complementary to the base in the target position. Release of pyrophosphate is detected enzymatically and pyrophosphate detection enzyme(s) are included in the polymerization step.
