WebThe electrophoretic trapping is a balance between the electrophoretic force (pulling the circular plasmid DNA against the trap) and diffusion (allowing the circular plasmid DNA to escape a trap). So, large circular molecules have a greater chance to get trapped than smaller DNA forms. WebLinks are provided below to general information on microbial source-tracking and detection techniques, such as ribotyping (DNA fingerprinting), genetic enterovirus detection using PCR/rtPCR and IC/PCR, and pulse field gel electrophoreses (PFGE).
