Abstract

© 2022 International Union of Biochemistry and Molecular Biology, Inc.This study developed an aptamer-based enzyme-linked immunosorbent assay (ELISA) system for sensitive detection of the d -dimer molecule, which is significantly elevated in several severe diseases. Aptamers are known to have advantages, such as longer stability and usability at different temperatures and in different complex samples, over antibodies, which are generally used in traditional ELISA methods. In the present work, the aptamer-based ELISA system was capable of quantitatively determining in a wide range (100 ng/ml─10 μg/ml) and remain stable for a couple of months even under ordinary room conditions. Validation of the developed system was evaluated by spiked human serum samples with high accuracy. With more comprehensive project steps, the developed aptamer-based ELISA system could be transformed into a platform that offers a sensitive, portable, and easy-to-use tool for analyzing d -dimer molecules.
