Cell Line Models
Applied StemCell’s (ASC) 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 cell line and animal 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.
The TARGATT™ system has been integrated into the TARGATT™ Master iPSC Line. The TARGATT™ Master iPSC Line was engineered from our well-characterized control human iPSC line, ASE-9211 (a NIST iPSC). The master cell line carries an “attP” integrase recognition landing pad in the H11 safe harbor locus. When used in conjunction with an “attB” containing donor plasmid and integrase expression, this master cell line enables site-specific integration of a transgene (up to 22kb) with very high efficiency.
In addition, the TARGATT™ site-specific knockin technology to engineer two additional TARGATT™ Master Cell Lines. The TARGATT™ Master CHO and HEK293 Cell Lines enable single-copy insertion at a safe-harbor locus (H11, ASC2). High integration efficiencies and medium to high levels of protein expression have been observed. These cell lines have the capacity to generate libraries for antibody screening. ASC can produce the library that best fits your project needs, or you can build your own library with the TARGATT™ CHO-K1 Kit (H11) or TARGATT™ HEK293 Kit (H11) for antibody library screening.
ASC is in the process of getting GLP and GMP certified and complied with. We now offer a wide range of GMP clinical-grade induced pluripotent stem cell (iPSC) related services. Applied StemCell’s GMP Grade iPSC line (Cord Blood CD34+, Male) can be engineered to express almost any gene of interest using TARGATTTM, but ASC can also conduct gene-editing services with the iPSC lines provided by customers. GMP grade knockin cell line generation service using the TARGATT™ Master iPSC Line is also available for single-copy gene insertion at a safe harbor locus.
*If you would like to work with your favorite cell line, ASC can engineer the target system into the cell line of your choice!
TARGATT™ Cell Line Advantages:
- Single copy knockin: 1 cell, 1 docking site, 1 inserted transgene

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.Genetically Modified Cell Lines / Isogenic Cell Lines Categories
