Partnership and Licensing

TARGATT™ Partnership/Licensing Programs

Unlike commonly used gene editing methods, TARGATTTM technology enables site-specific integration of any gene of interest (GOI) up to 20kb at a pre-selected safe harbor locus with high efficiency. Single-copy integration of the GOI is facilitated by a unique integrase. Additionally, we have observed uniformed and medium to high levels of expression in iPS, HEK293, and CHO cells following stable insertion. 

Applied StemCell, Inc. (ASC) has exclusive rights for TARGATTTM  from Stanford University. Dr. Ruby Chen-Tsai, Ph.D., ASC’s President and CEO, and Dr. Alfonso Farruggio, Ph.D., Head of Research and Development, are co-inventors of the knock-in technology, TARGATTTM.  When you partner with ASC, you don’t have to worry about obtaining any additional licensing, and you will receive full support from the scientists who worked directly on developing the gene-editing system. Licensing and partnership opportunities are available for preclinical research, product development, and biotherapeutic development worldwide.
