    • In one aspect, the present invention relates to a method for obtaining structural information about an encoded molecule. The encoded molecule may be produced by a reaction of a plurality of chemical entities and may be capable of being connected to an identifier oligonucleotide containing codons informative of the identity of the chemical entities which have participated in the formation of the encoded molecule. In a certain embodiment, primers are designed complementary to the codons appearing on the identifier oligonucleotide, and the presence, absence or relative abundance of a codon is evaluated by mixing a primer with the identifier oligonucleotide in the presence of a polymerase and substrate (deoxy)ribonucleotide triphosphates measuring the extension reaction. In another aspect, the invention provides a method for selecting compounds which binds to a target. More specifically, the invention relates to a method in which a target associated with an oligonucleotide initially is mixed with a library of complexes, each complex comprising a display molecule and an oligonucleotide identifying said display molecule. Next, due an increased proximity, the target oligonucleotide is coupled to the identifier oligonucleotide of complexes having a display molecule with affinity towards the target. In a final stage the coupled nucleotides are analysed to deduce at least the identity of the display molecule.
    • 一方面,本发明涉及获得关于编码分子的结构信息的方法。 编码的分子可以通过多个化学实体的反应产生,并且可以能够连接到含有密码子的标识符寡核苷酸,该密码子包括参与编码分子形成的化学实体的身份。 在一些实施方案中,设计引物与出现在标识寡核苷酸上的密码子互补,并且通过在聚合酶和底物(脱氧))存在下将引物与标识寡核苷酸混合来评估密码子的存在,不存在或相对丰度, 核糖核酸三磷酸测量延伸反应。 另一方面,本发明提供了选择与靶标结合的化合物的方法。 更具体地,本发明涉及一种方法,其中与寡核苷酸相关的靶标最初与复合物文库混合,每个复合物包含显示分子和识别所述显示分子的寡核苷酸。 接下来,由于接近度增加,靶寡核苷酸与具有与靶具有亲和性的显示分子的复合物的标识符寡核苷酸偶联。 在最后阶段,分析耦合的核苷酸以至少推断显示分子的身份。
