ASC’s proprietary TARGATT™ transgenic mouse model generation products offer an affordable do-it-yourself option to generate site-specific transgenic mice very efficiently and in as little as 3 months, in your own animal facility. You can purchase all required components to generate your transgenic "knock-in" mice right here from our ASC website: TARGATT™ mice, TARGATT™ plasmids, transgenic kits for site-specific knock-in of your transgene, and genotyping kits. The TARGATT™ products are manufactured in our ISO:9001 quality management system certified facility.

Transgenic core facilities currently using the TARGATT™ system, including UCSF, NIH, MaxPlank, Harvard, Colombia and many more!

  • TARGATT™ Plasmids

    We offer a wide range of plasmids for our TARGATT™ Transgenic Knock-in Mouse applications. Our TARGATT™ plasmids are engineered to contain various promoters and marker gene combinations to best meet your needs when generating your transgenic mouse.

  • TARGATT™ attP Mice

    This transgenic mouse line contains an attP site at the H11 loci for easy site-specific gene knock-in and is available for purchase from Charles River. Make your own TARGATT™ knock-in mouse for gene overexpression, reporter gene insertion, knock-down by siRNA, humanized models and other applications. TARGATT™ attP Mice are available in the C57BL6 background.

  • TARGATT™ Transgenic Kits

    TARGATT™ Transgenic Kits are essential for the generation of TARGATT™ knock-in mice. The kits contain PhiC31 integrase mRNA, control mRNA and buffer and are designed for the microinjection of a TARGATT™ plasmid into the pronuclei of TARGATT™ Transgenic Mouse embryos.

  • TARGATT™ Genotyping Kit

    The TARGATT™ Mouse Genotyping Kit allows for convenient genotyping of TARGATT™ Transgenic Mice via tail biopsy. Use this kit to confirm the presence of an attP knock-in site (H11 or ROSA26) and/or the integration of a transgene into the TARGATT™ Site.

Our proprietary site-specific DNA integration system, TARGATT™ lets you create site-specific transgenic mice in a more efficient and faster way compared to traditional methods. Generating a transgenic mouse (e.g. knock-in mouse) by conventional methods like pronuclear microinjection or lentiviral injection has several limitations, one of them being 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. Furthermore, random transgene insertion in the transgenic mouse usually happens in multiple copies, resulting in repeat induced silencing and genomic instability. The TARGATT™ technology uses PhiC31 integrase to insert any gene of interest into a specific docking-site that was pre-engineered into an intergenic and transcriptionally active genomic locus. Applied StemCell can create site-specific knock-in mice for you in as little as 3 months. Using our novel TARGATT™ system, a gene of interest can be inserted at a well-characterized, transcriptionally-active locus in the mouse genome with guaranteed transgene expression. Our scientists at Applied StemCell can create a TARGATT™ mouse for you, or you can purchase the animals and reagents to make your own. The TARGATT™ products for mouse model generation are manufactured in our ISO:9001 certified facility in the USA under strict quality controlled protocols and regulations.

Fast! Reliable! Advantages of TARGATT™ Technology

  1. High integration efficiency mediated by PhiC31 integrase reduces time and cost.
  2. Site-specific integration at a pre-selected genomic locus eliminates position effect and ensures high expression levels of the transgene.
  3. Integration at intergenic region ensures that no internal genes are interrupted.
  4. Single copy gene integration eliminates repeat-induced gene silencing and genomic instability.
  5. Site-specific integration allows a precise comparison of the effects of the transgenes among different lines.
