How does ribotyping work

WebA ribotype is essentially an RFLP consisting of the restriction fragments from a particular genome, which contain rRNA genes. To obtain a ribotype for an organism, it must first be cultured to obtain enough cells for the procedure. Total DNA is then isolated within the riboprinter and is totally restricted using a restriction enzyme. 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.
