TARGATT™ Rapid and Efficient Transgene Integration Technology: Stable Cell Line Development and Generation of Large Mammalian Cell-based Screening Libraries

Applied StemCell's TARGATT™ site-specific transgene knockin technology provides a very efficient platform for stable cell line generation and for mammalian cell-based library screening. Based on our very successful TARGATT™ transgenic mouse model generation platform, the TARGATT™ cell line generation involves the generation of TARGATT™ Master Cell Lines that are engineered to carry an integrase recognition landing pad, "attP" in a preselected, intergenic, safe harbor locus. The TARGATT™ integrase then mediates a unidirectional recombination between the attP sites in the cell line and attB sites on the donor plasmid to integrate the gene of interest into the specified locus with very high efficiency (which translates to library sizes) and more importantly only one copy of the gene is inserted.

Topics covered in this short video:

  • Importance of mammalian screening libraries and advantages of integrase for transgene insertion
  • TARGATT™  technology for site-specific gene knockin
  • TARGATT™ Master Cell Line for transgene knockin 
  • Evaluation of various docking site (landing pad) loci for high level protein expression
  • Expression of a Fc fusion protein
  • Potential applications for the TARGATT™ mammalian library screens

How-to Guide for TARGATT™ Transgenic Kit, by Dr Ruby Chen-Tsai

The TARGATT™ Transgenic Kit is designed to create site-specific knock-in transgenic mice at a defined chromosomal locus in a more efficient and significantly faster way over traditional methods. Generating transgenic mice by conventional methods (e.g. pronuclear microinjection or lentiviral injection) has following limitations, first of which is random insertion of the transgene. Random insertion of a transgene results in position effect where either the transgene is prone to silencing or endogenous gene expression is disrupted. Secondly, transgenes can be inserted as multiple copies, resulting in instability at the insertion locus. Using our proprietary site-specific DNA integration system, TARGATT™, combined with our genetically engineered TARGATT™ mice (strain code 549), you can generate your desired trangenic mouse models with guaranteed gene expression in as little as three months.

This video gives a step-by-step overview on how to use the TARGATT™ Trangenic Kit and the TARGATT™ technology to generate site-specific knock-in mouse models.

Human iPSC-based Disease Modeling & Drug Screening for Neurodegenerative Disorders

Human induced pluripotent stem cell (iPSC) technology offers the benefits of a cell line coupled with the advantage of using human primary cells. Additionally, iPSCs are also amenable to genome editing, and engineered iPSCs and their isogenic control lines can be terminally differentiated into cells of multiple lineages. This presents an almost limitless access to relevant and predictive disease models for basic research, drug discovery, toxicity screening and hopefully for regenerative cell therapy. In this webinar, we will elaborate on a panel of iPSC lines engineered for neurotoxicity assays and disease modeling. The cell lines in this panel include: 1) control lines, 2) patient-specific lines, 3) lineage-specific knock-in reporters, 4) isogenic controls of single and double knock-outs. We have also established scalable protocols for generating differentiated cells in an assay ready format. This talk will focus on the utility of these lines for neurotoxicity assays, including assays to determine the specificity of different neural cell types for a small range of chemicals and drugs from the Tox21 library, as well as for neuroprotective assays with dopaminergic neurons.

Using autobioluminescent cells to reduce the cost and complexity of optical imaging

Autobioluminescent cells use a genetically encoded synthetic luciferase cassette to continuously produce a bioluminescent signal without the need for extracellular stimulation. By encoding both a luciferase protein, as well as a short synthetic pathway capable of transforming natural intracellular products into luciferin substrates, these cells can self-modulate their bioluminescent production in response to metabolic activity levels, or autonomously enact their bioluminescent phenotype in response to intra- or extracellular events. The use of this self-directed approach to bioluminescent imaging improves upon traditional reporters such as firefly luciferase (luc) by negating the need for light activating chemical substrate addition, which reduces the cost of performance while simultaneously increasing the amount of data that can be obtained per run. This eliminates the need for sample destruction or any investigator interaction, allowing for ultra-simplistic, low-cost bioluminescent screening using existing optical imaging equipment. This webinar will discuss the capabilities and uses of autobioluminescent cells for improving existing bioluminescent imaging workflows and for developing new workflows that leverage the autonomous signal generation phenotype to gather data not available from traditional optical imaging reporter platforms.

Highlights of this webinar:

  • An introduction to autobioluminescence
  • Autobioluminescent vs. bioluminescent imaging
  •  Using autobioluminescence for in vitro applications
  •  Using autobioluminescence for in vivo applications
  •  Autobioluminescent expression in stem cells
  •  Conclusions
