Nucleic acid strand displacement for indirect determination of foodborne bacteria by capillary electrophoresis and its application in antagonism and bacteriostasis studies

Shaoyan Zhang,

et al.

Abstract: Foodborne bacteria threaten human's health. Capillary electrophoresis (CE) is a powerful separation means for the determination of bacteria. Direct separation of bacteria suffers from the shortages of low resolution, channel adsorption, and bacterial aggregation. In this work, a method of nucleic acid strand displacement was developed to indirect separate the bacteria by CE. DNA complexes, consisting of probes and aptamers, were mixed with the three bacteria Staphylococcus aureus, Escherichia coli, and Pseudom… Show more

“…By separating these duplexes with different lengths, indirect separation of miRNAs becomes a feasible task. In our prior study [20], indirect separation was developed for the determination of bacteria. However, the signal amplification was not explored to further improve the detection sensitivity.…”
