Abstract

Ovarian cancer biomarker CA125 is widely used to diagnose and monitor ovarian cancer. In order to develop novel diagnostic and therapeutic tools, nucleic acid aptamers with high affinity to CA125 were selected using One-Pot based systematic evolution of ligands by exponential enrichment (One-Pot SELEX). After several rounds of One-Pot SELEX, selected aptamers were sequenced using high-throughput sequencing and analyzed. Dissociation constants of selected aptamers were determined using affinity probe capillary electrophoresis and fluorescence anisotropy. This work is supported by the National Cancer Institute.
