    • This invention relates generally to systems and methods for identifying and selecting, desired proteins or nucleic acid molecules by linking mRNA, with known or unknown sequences, to its translated protein to form a cognate pair. The cognate pair is selected based upon desired properties of the protein or the nucleic acid. This method also includes the evolution of a desired protein or nucleic acid molecule by amplifying the nucleic acid portion of the selected cognate pair, introducing variation into the nucleic acid, translating the nucleic acid, attaching the nucleic acid to its protein to form a second cognate pair, and re-selecting this cognate pair based upon desired properties. Modified mRNAs operable to crosslink to tRNAs are also provided. Methods of producing a psoralen monoadduct or a crosslink are also provided. Methods of producing mRNA libraries and vaccines are also provided.
    • 本发明一般涉及用于通过将mRNA与已知或未知序列连接至其翻译的蛋白质以形成同源对来鉴定和选择所需蛋白质或核酸分子的系统和方法。 根据蛋白质或核酸的期望特性选择同源对。 该方法还包括通过扩增所选同源对的核酸部分,将变异引入核酸,翻译核酸,将核酸附着到其蛋白质以形成第二同源物,从而产生期望的蛋白质或核酸分子 对,并基于期望的性质重新选择该同源对。 还提供了可操作以交联至tRNA的修饰的mRNA。 还提供了生产补骨脂素单加成物或交联的方法。 还提供了产生mRNA文库和疫苗的方法。
