ImPaqT, a Golden Gate-based immunological toolkit for zebrafish transgenesis
Transgenic animals play an essential role in many aspects of zebrafish research. Here, we have developed ImPaqT ( Im munological Toolkit for Paq CI-based Golden Gate Assembly of Tol2 T ransgenes), a new Tol2-based transgenesis system that utilizes Golden Gate assembly to facilitate the production of transgenic zebrafish lines. This system allows for rapid assembly of multiple fragments into a…
A groundbreaking immunological toolkit for zebrafish transgenesis has been introduced by a team based in Golden Gate. The ImPaqT (Immunological Toolkit for Paq CI-based Golden Gate Assembly of Tol2 Transgenes) system leverages Golden Gate assembly to streamline the creation of transgenic zebrafish lines. This innovative approach enables the rapid assembly of multiple genetic fragments into a single transgene, simplifies the swapping of individual sequences for new transgenes, and streamlines the cloning workflow for incorporating novel genetic elements into existing kits.
Within this framework, researchers have developed reagents to achieve gene expression in various cell types, a collection of top-tier fluorescent proteins to monitor cell populations and transgenes, and tools to facilitate genetic manipulation, purification, and targeted cell ablation. Unlike many recombination-based systems, ImPaqT's expandable design accommodates complex constructs such as multifragment promoters, all within the established modular structure of the toolkit.
The system's effectiveness was demonstrated through the generation of diverse transgenic immune reporter lines. While the initial focus was on the immune system, a burgeoning field of zebrafish research, ImPaqT's adaptability extends to the construction of virtually any zebrafish transgene, providing the zebrafish community with a powerful new set of tools.
