iPSC Genome Editing Rapid Automated Cell Line Editing (RACE™)

This short webinar highlights Applied StemCell’s (ASC) highly acclaimed, stem cell genome editing service to generate physiologically relevant in vitro models using iPSCs and CRISPR/ Cas9. The video showcases our ability to induce or correct mutation with standard genetic modifications (such as knockout, knock-in, and point mutation) as well as complex genome engineering such as gene fusion. Furthermore, our high throughput automated process enables higher volume projects, better picking accuracy, reduced hands-on time and errors leading up to 60% faster project timelines and 98% success rate. Applied StemCell also offers master cell lines with proven genome editing and differentiation capacity, and downstream differentiation to many cell lineages.

Topics covered in this short video:

  •  Integrated end-to-end-solutions for iPSC related projects
  • Isogenic cell line model development
  • High throughput genome editing with automation and workflow optimization
  • Examples of gene modifications in patient and healthy iPSCs
  • Downstream differentiation to various lineages


TARGATT™: A Mammalian Cell Library System for Antibody/ Protein Screening

Mammalian cell-based libraries offer a physiologically relevant context for high throughput screening of high affinity antibodies. Current technologies using retroviruses to develop mammalian cell libraries result in random, multiple copy integration at various loci of the genome. As a result, the expression level amongst different cells in the library is varied leading to false representation of the binding affinity of individual molecules. In this talk, we introduce the TARGATT™ site-specific, integrase-mediated gene integration technology which provides an efficient strategy for integrating a gene of interest into a preselected, transcriptionally active locus. A TARGATT™-HEK293 master cell line was generated to enable knock-in of only a single copy of the transgene in every cell at the same locus, with efficiency over 90%. The TARGATT™ system thus provides an efficient platform with uniform transgene expression and reproducibility for constructing large isogenic cell libraries for rapid, high throughput antibody screening. The same system can also be used for bioproduction, protein evolution, target validation and safety assessment in immuno-oncology, GPCR and ion channels.

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.

  • 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
