    Targatt services

    Based on our proprietary TARGATT Technology for site-specific knock-in mouse generation, we developed a TARGATT system specifically for introducing gene(s) of interest into mammalian cell lines. The unique advantage of this system is that any gene of interest can be inserted efficiently into a defined, transcriptionally-active locus with high gene expression in a single copy fashion.

     TARGATT Features:

    • Site-specific insertion of any gene 
    • High integration efficiency
    • Single-copy integration
    • Stable expression
    • Fast: get your transgenic cell line in 3 months!

    targatt-antibodies-gentaur-knockin-knockout-mouse-1

    Targatt proprietary TARGATT Technology enables highly efficient site-specific gene integration in mammalian cells and animals. This 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. Our TARGATT Technology improves several aspects in the generation of transgenic cell lines and animals:

    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.

    TARGATT Technology can be utilized for a variety of applications including reporter gene expression, gene knockdown and disease models.

    Knock-in and Knock-out Rat

    Targatt provides a complete range of gene targeting services in rats to generate transgenic knock-in and knock-out rat models.

    Rats are more versatile research model animals than mice since they are physiologically more similar to humans. The recent isolation of rat embryonic stem (ES) cells opened the doors to the generation of transgenic rats and we are proud to be one of the first providers of an all-inclusive transgenic rat generation service. Our competence in gene-targeting vector design coupled with our expertise in culturing rat ES cells allows us to offer a high-quality customized service for the generation of transgenic knock-in and knock-out rats.

    Using our proprietary germline competent rat ES cell lines we can create your customized transgenic rat model, including

    • - Constitutive knockin/out
    • - Conditional knockin/out
    • - Inducible knockin/out
    • - Point mutations
    • - Random integration
    • - Insertion of reporter genes
    • - Humanized rat models
    • - Disease rat models
    • knock-in-knock-out-mouse-targatt-1

     

    We take great pride in offering you the highest level of service and we are committed to ensuring the success of your transgenic rat project. Our service includes an initial project assessment based on your model requirements. A dedicated PhD level project manager will discuss available gene targeting vector design strategies and will update you continuously throughout the project.

    We provide the most flexible customized service options whether you’d like us to do all the work or are on a tight budget and prefer doing some steps yourself.

     Full Transgenic Rat Generation Service Includes:

    • - Gene targeting vector design, construction and sequencing
    • - Rat ES cell targeting, screening and expansion of positive rat ES cell clones
    • - Karyotyping of targeted rat ES cells

    Random Transgenic Mouse

    We provide a service to generate transgenic mice by traditional pronuclear microinjection. Using this method, transgenes are inserted randomly into the genome.

    Expression of the transgene and the subsequent transgenic mouse phenotype may vary from line to line due to the nature of random gene insertion. We recommend to generate multiple independent trangenic mouse lines in order to interpret the experimental results.

    Available mouse strains: FVB, C57BL/6

    We also offer Knock-in and Knock-out Mice and Knock-in and Knock-out Rat services. For more information please contact us.

    Generation of transgenic mice by random insertion

    Step 1: Cloning of cDNA, promoter of interest, and other elements

    Step 2: Construction of the transgene vector

    Step 3: Pronuclear microinjection of vector DNA into mouse embryos

    Step 4: Transfer of injected embryo into recipient mothers

    Step 5: Genotyping of offspring to identify potential transgenic founders

    Step 6: Breeding to F1 or F2 progenies (optional)

    Project: Germline-transmitted, conditional knock-out mice by tetraploid complementation

    "Overall, I am very satisfied with the quality of your service. After we received the mice, we did extensive studies to characterize them. All of the PCR reactions confirm the gene modifications are in the correct sites. We have also crossed mice with Cre mice to demonstrate that the Cre deleted the exon in heterozygous pups as expected. All data obtained showed that the mice were correctly targeted. In addition, I am very happy with the frequent communication with your scientists during the process. I highly recommend your services."

    Knock-in Mouse Models

    The introduction of a gene into a specified location of the mouse genome can be used for various applications. Mice can be homozygous or heterozygous for the inserted gene.

    • - Reporter genes (e.g. GFP, lacZ) are used for expression analysis of a gene of interest. The reporter gene is inserted into the gene of interested in-frame (non-disruptive), allowing for visualization of temporal and spatial gene expression pattern.
    • - Humanized disease models can be generated by inserting a human mutant gene or gene fragment into the corresponding mouse gene. The diseased human allel is thus transcribed in the appropriate genomic context and can be analyzed on behavioral, pathological, cellular and/or molecular level.
    • - DNA recombinases (CRE, FLP) can be inserted into a gene of interest. The celltype-specific expression of the recombinase then allows for gene inactivation in the desired tissue after crossing this knock-in mouse with a conditional knockout mouse.

     

    Knock-out Mouse Models

    The knockout technology is most commonly used for gene inactivation, either in a constitutive or conditional fashion.

    • - Constitutive knock-out mouse models are widely used to study gene function. The gene of interest is permanently inactivated in all cells of the animal. However, this non-conditional knock-out may cause lethality and is therefore not always recommended.
    • - Conditional knock-out models are inducible - the targeted gene is excised after crossing the mouse with a Cre-transgenic mouse line. Gene inactivation can be celltype-specific and/or chemically induced.
