Method for the synthesis of a bifunctional complex

摘要

A method for synthesising a bifunctional complex which comprises a reaction product and an encoding region. The complex is a hybridisation product between a nascent bifunctional complex and a building block. The nascent bifunctional complex comprises an attachment entity linked to an oligonucleotide identifier region and the building block comprises a fuctional entity attached to an oligonucleotide which is sufficiently complementary to the identifier region to allow for hybridisation . The functional entity may then be transferred to the attachment entity by a chemical reaction.The complementary identifier region further comprises a unique codon, which identifies the functional entity unequivocally. This codon functions as a template for forming a unique codon as an extention of the identifier region by use of an enzime, such as a polymerase. The unique codon may be used to decode the synthetic history of the reaction product after several cycles of transfer of functional entities.
