Key Benefits of Zebrafish Tol2 Transgenesis

Compared to other methods, inserting large content in the zebrafish genome using the Tol2 transposon-based system offers advantages for integrating larger DNA fragments into the zebrafish genome. This system allows researchers to introduce and study genes, regulatory elements, or other genetic elements that may be relatively large in size, providing opportunities to investigate complex genetic interactions and gene functions.

Tol2 Transgenesis Service Process

Leveraging the Tol2 transposon system, derived from medaka fish, we provide a reliable and efficient method for creating transgenic zebrafish models that enable you to:

  • Generate Cre Recombinase-Driver lines for precise genetic targeting.
  • Create transcriptional reporters to investigate gene expression in specific tissues.
  • Develop models to control the timing of gene expression, providing insights into dynamic biological processes.
  • Generate humanized zebrafish models for studying human genome variations and diseases.

Tol2 Transgenesis Service FAQS

The Zebrafish Tol2 transgenesis service is a specialized service that enables the efficient and precise integration of transgenes into the zebrafish genome using the Tol2 transposon system.

The Tol2 transposon system utilizes a DNA sequence called the Tol2 transposon, which can "jump" or transpose from one location to another in the zebrafish genome edits. This system allows for the stable and heritable integration of transgenes.

The service offers several benefits, including high efficiency in generating transgenic zebrafish, precise insertion of transgenes or expression cassettes at desired genomic locations, and the ability to study gene function, disease models, and developmental processes.

The timeline for the service may vary depending on the specific requirements and complexity of the project. Generally, the process involves plasmid construction, microinjection into zebrafish embryos, and subsequent screening and validation. The duration can range from a few weeks to a couple of months.

Yes! The service allows for the integration of custom transgenes, including reporter genes, fluorescent markers, or genes of interest. Researchers can provide their own transgene constructs, and the service will facilitate their integration into the zebrafish genes.
