CGE Service

Capillary Gel Electrophoresis

A powerful, fast and reliable method to evaluate plasmid topologies within your plasmid DNA sample

PlasmidFactory offers determination of the three most common plasmid forms (ccc-monomer, ccc-dimer, oc-forms). This CGE Service is offered in combination with our contract manufacturing service as well as for your self-made plasmid DNA.

The CGE analysis is already included in the standard QC of our CCC grade (CCC grade basic and CCC grade classic) and HQ plasmids. For Research grade plasmids the CGE Service is available on request. Furthermore, the CGE service can be included in our Storage & Logistics service to monitor plasmid DNA stability during storage.

Count on PlasmidFactory’s longtime experience in plasmid DNA analysis by CGE and experience the benefits of this unique technology in your routine laboratory processes.

Capillary gel electropherogram and different types of plasmid topology:

A – B: ccc-forms (monomer and dimer)C – D: linear-forms (monomer and dimer)E - F: oc-forms (monomer and dimer)

CGE analysis is a proprietary analytical tool of PlasmidFactory and is the only reliable method to quantify plasmid forms.

Scientific research is one of the most exciting and rewarding of occupations. It is like a voyage of discovery into unknown lands, seeking not for new territory but for new knowledge. It should appeal to those with a good sense of adventure.
