    摘要: The present invention relates to compositions involving randomized in-frame fusion polynucleotides and their introduction into a host organism to identify desirable phenotypic changes. The present invention further relates to methods of generating these randomized in-frame fusion polynucleotides by introducing randomized in-frame fusion polynucleotides into an organism, selecting for organisms with new or altered phenotypes, re-isolating the randomized in-frame fusion polynucleotides from the selected organisms, re-assembling the constituent polynucleotides of the re-isolated randomized in-frame fusion polynucleotides into new collections of randomized in-frame fusion polynucleotides, and repeating the selection for organisms with new or altered phenotypes.

    摘要: The invention concerns a chemical compound comprising a chemical moiety (p) capable of performing a binding interaction with a target molecule (e.g. a biological target) and further comprising an oligonucleotide (b) or functional analogue thereof. In a first embodiment according to the invention, the chemical compound is characterized in that the oligonucleotide (b) or functional analogue comprises at least one self-assembly sequence (b1) capable of performing a combination reaction with at least one self-assembly sequence (b1′) of a complementary oligonucleotide or functional analogue bound to another chemical compound comprising a chemical moiety (q). In a second embodiment according to the invention, the chemical compound which comprises a coding sequence (b1) coding for the identification of the chemical moiety (p) is characterized in that the chemical compound further comprises at least one self-assembly moiety (m) capable of performing a combination reaction with at least one self-assembly moiety (m′) of a similar chemical compound comprising a chemical moiety (q). The invention comprises corresponding libraries of chemical compounds as well as methods of biopanning of target molecules and of identifying such targets.
