"Another company that has benefitted from Inovio’s newfound attention isOncoSec Medical (OTC: ONCS) – a newer “offshoot” company that uses a similar but distinctly different electroporation device known as the OncoSec Medical System (OMS) that is based on Inovio’s technology. The specific amplitude and frequency of the OMS electroporation is calibrated such that plasmid delivery into solid tumor masses is fully optimized, while CELLECTRA electroporation is less specialized and focus more on the vaccination of skin cells. The cross-license agreement made between Inovio and Oncosec also covers the two devices for their distinctly different applications."
I guess the CELLECTRA hand held device is an improvement to electroporation. Several actually use the technology, most have not perfected it in a way that INO has, however.
"Inovio Biomedical Corporation (NYSE Amex: INO), a leader in DNA vaccine design, development and delivery, has unveiled its new CELLECTRA®-SP series of hand-held, cordless electroporation devices at the DNA Vaccines 2010 conference being held in New Orleans, LA.
Existing generations of electroporation systems consist of an electrical pulse generator box the size of a large laptop attached by a cord to a separate needle-electrode applicator. The new CELLECTRA®-SP devices bring together groundbreaking design and engineering advancements to combine all components into a self-contained, easy-to-use portable device the size of a cordless hand tool.
