    • This invention relates to a method of producing a purified polymer selected from the group consisting of PNAs, (poly)peptides, PNA chimera, peptide-DNA chimera, and derivatives thereof, wherein the polymer carries at least one lipophilic group and wherein the method comprises the following steps: (a) transferring a solution comprising the polymer carrying a lipophilic group to a lipophilic surface under conditions that allow binding of said lipophilic group to said lipophilic surface; (b) washing said surface under conditions that allow said binding to be maintained, wherein polymers not carrying said lipophilic group are removed; (c) washing said surface under conditions that break said binding; (d) collecting the washing solution from step (c); and (e) obtaining said purified polymer from said washing solution. Preferably, the lipophilic group is a protection group, or a label such as a fluorescent dye, or a linker, for example a linker suitable for immobilization on a support.
    • 本发明涉及一种制备纯化聚合物的方法,该纯化聚合物选自PNA,(poly)肽,PNA嵌合体,肽-DNA嵌合体及其衍生物,其中聚合物携带至少一个亲脂基团,其中该方法包括 以下步骤:(a)在允许所述亲脂基团与所述亲脂性表面结合的条件下将包含携带亲脂基团的聚合物的溶液转移到亲脂性表面; (b)在允许所述结合保持的条件下洗涤所述表面,其中除去不携带所述亲脂基团的聚合物; (c)在破坏所述结合的条件下洗涤所述表面; (d)从步骤(c)收集洗涤溶液; 和(e)从所述洗涤溶液中获得所述纯化的聚合物。 优选地,亲油基团是保护基团,或诸如荧光染料的标记或接头,例如适于固定在载体上的接头。
