Targeted Collection of Plasmid DNA in Large and Growing Animal Muscles 6 Weeks after DNA Vaccination with and without Electroporation

Figure 2

Sampling of the injection point 6 weeks after injection. Six weeks after injection, the injection point was localized as done at the injection time (Figure 1). The two lines were drawn thanks to the four tattooed points. After removing the skin and the fat layer, the portion of the injected muscle was sampled using a disposable 2 cm long biopsy punch that was horizontally applied on the muscle surface.
