Applied StemCell’s proprietary TARGATT™ technology, enables fast and site-specific, stable integration of large DNA fragments into an intergenic, transcriptionally active safe harbor locus with very high efficiency. The TARGATT™ gene editing platform is versatile and can generate large fragment knock-in animal or cell line models. This technology circumvents problems associated with random integration such as position effect, and gene silencing or instability due to integration of multiple copies of the transgene. Applications for TARGATT™ models:  Transgene overexpression models, humanized gene knockin, reporter gene knock-in, conditional knock-in, inducible expression, and Cre-driver lines.

The traditional CHO antibody production and animal bioproduction methods are inefficient because they require random gene insertion and forced amplification of transgenes. Applied StemCell has addressed these problems by utilizing our expertise in cell line and animal model engineering with our proprietary TARGATT™ technology to develop two bioproduction methods: TARGATT™ CHO Master Cell Lines and Transgenic TARGATT™ Rabbits. Both methods offer low-cost, efficiency, consistent protein expression and high protein yield that is easily scalable for large scale bioproduction.

Isogenic cell lines represent a unique toolset for studying cellular biology, such as the impact of genotype on cellular phenotype, as well as for parallel, high throughput screening to enable the discovery of therapeutic compounds that exhibit genotype-specific toxicity.  An isogenic cell line is a cell line that has been engineered from a parental line through the introduction of a targeted gene mutation. In doing so, the parental cell line inherently becomes a control line to which the engineered line can be referenced. Applied StemCell provides ready-to-use engineered cell lines for cancer and neurodegenerative research as well as reporter lines for quantitative assessments of drug screening experiments.
