Identification and characterization of two high affinity aptamers specific for Salmonella Enteritidis

DNA aptamers are promising candidates for bio-recognition assays due to their accumulation of bacterial cells. This feature can be used to identify specific pathogens in food samples. However, the conventional process of aptamer screening by randomly picking bacterial plate colonies for Sanger sequencing risks the elimination of superior sequences. In this study, we screened and evaluated all aptamers that were targeted to Salmonella Enteritidis...
