本發明提供一種對卵巢癌細胞具有專一性之適合體,其是由系統性配分子指數增益演繹程序(Systematic evolution of ligands by exponential enrichment,SELEX)與微流體晶片系統體外篩選而得。該些適合體更可分別結合不同組織學型態的卵巢癌細胞,且具有高結合率。因此本發明之適合體不僅可用於檢測卵巢癌細胞,亦可用於識別不同組織型態之卵巢癌細胞。 The present invention provides ovarian cancer-specific aptamers, which were selected in vitro using SELEX and a microfluidic chip system. The aptamers can also bind to different histologically-classified ovarian cancer cells with high affinity accordingly. Therefore, the aptamers of the present invention and the application thereof can not only be used in detection of ovarian cancer cells but also be applied in recognition of different histologically-classified ovarian cancer cells. |
