Serum-compatible screening and truncation optimization of copeptin aptamers for TdT-amplified fluorescent detection.
Copeptin is a clinically relevant biomarker for early diagnosis and prognostic assessment of acute myocardial infarction (AMI). Traditional antibody-based assays suffer from long testing time, high cost and complicated operation. Herein, we first screened high-affinity copeptin aptamers under serum-mimicking conditions...
