A validated model of in vivo electric field distribution in tissues for electrochemotherapy and for DNA electrotransfer for gene therapy.
Permeabilising electric pulses can be advantageously used for DNA electrotransfer in vivo for gene therapy, as well as for drug delivery. In both cases, it is essential to know the electric field distribution in the tissues: the targeted tissue must be submitted to electric field intensities above the reversible permeabilisation threshold (to actually permeabilise it) and below the irreversible...
متن کاملAn Efficient Method For DNA Extraction From Paraffin Wax Embedded Tissues For PCR Amplification Of Human And Viral DNA
Background and Objective: Formalin-fixed paraffin-embedded tissues are a valuable source of DNA for molecular studies. We designed and optimized an efficient procedure for DNA extraction from formalin-fixed paraffin embedded tissues. Materials and Methods: Seventy three blocks of cervical paraffin-embedded tissues were investigated. DNA was extracted using 45 minutes boiling in alkaline sol...

15 صفحه اولMechanisms of in vivo DNA electrotransfer: respective contributions of cell electropermeabilization and DNA electrophoresis.
Efficient cell electrotransfection can be achieved using combinations of high-voltage (HV; 800 V/cm, 100 micros) and low-voltage (LV; 80 V/cm, 100 ms) pulses. We have developed equipment allowing the generation of various HV and LV combinations with precise control of the lag between the HV and LV pulses. We injected luciferase-encoding DNA in skeletal muscle, before or after pulse delivery, an...
متن کاملOptimisation of intradermal DNA electrotransfer for immunisation.
The development of DNA vaccines requires appropriate delivery technologies. Electrotransfer is one of the most efficient methods of non-viral gene transfer. In the present study, intradermal DNA electrotransfer was first optimised. Strong effects of the injection method and the dose of DNA on luciferase expression were demonstrated. Pre-treatments were evaluated to enhance DNA diffusion in the ...
