The Tol2kit
Tol2kit v1.1, released August 2007
Generating stable transgenic zebrafish lines has historically been laborious, for three reasons:
- Building transgenesis constructs by conventional subcloning can be difficult, especially when using long coding or regulatory sequences
- Injecting plasmid DNA yields mosaic transient expression and low germline transgenesis rates
- When screening for stable integrations, transgenes that express fluorescent proteins (e.g. GFP) are easy to detect, but other transgenes are not.
The Tol2kit uses site-specific recombination-based cloning (multisite Gateway technology) to allow quick, modular assembly of promoter-coding sequence-3' tag constructs in a Tol2 transposon backbone.
It includes a variety of widely-useful entry clones, including hsp70 and beta-actin promoters; cytoplasmic, nuclear, and membrane-localized fluorescent proteins; and IRES-driven GFP cassettes for bicistronic expression. It includes two Tol2-based destination vectors, one with a cmlc2:egfp transgenesis marker.
About this site
This wiki provides the documentation for the Tol2kit; it is maintained by the Chien lab. Please bear with us; some sections are still under construction.
- Basic Gateway principles
- List of entry and destination clones
- Protocols
- Sample results with the Tol2kit
- Sources for the Tol2kit
If you have questions or comments about the Tol2kit, please post them on the Tol2kit blog. If you construct other entry or destination clones, we would love to post information about them here.
Clone distribution
We are freely distributing all of the plasmids described here. For reasons of convenience, we only distribute them as a complete set (25 plasmids), spotted as DNA onto filter paper. Since the destination vectors and transposase plasmid are all derived from Dr. Koichi Kawakami's original constructs, we ask that you please first contact Dr. Kawakami <kokawaka@lab.nig.ac.jp> and execute an MTA for use of the Tol2 transposase construct and plasmids based on Tol2.
We are also happy for labs to share these plasmids or pass them on to others, as long as you pass on the address of this wiki, and the receiving lab has executed a Tol2 MTA with Dr. Kawakami. We especially encourage different labs at the same institution to share plasmids. This reduces our workload (generating maxipreps and spotting plasmid) as well as yours (growing up clones).
To request the Tol2kit, please send an email to Chi-Bin Chien <chi-bin.chien@neuro.utah.edu>.
Citing the Tol2kit
A methods paper describing the Tol2kit has recently (September 2007) been accepted at Developmental Dynamics (download preprint). In the meantime, if you publish work using the Tol2kit, please contact Chi-Bin Chien for how to cite it.

Revision history
9/23/07 Added the Sources page. The wiki is now substantially complete and is entering a maintenance phase. We will continue to correct errors and add information on new clones as the kit evolves.
9/12/07 Added a preprint version of the Tol2kit methods paper; various other minor changes.
8/17/07 Wiki URL: to fix a problem that some users had with firewall blocking of the wiki, we have slightly reengineered access to the site. You now must add a forward slash to the end of the URL: http://chien.neuro.utah.edu/tol2kitwiki/
6/7/07 List of clones: columns for version numbers and MTAs have been added.
6/7/07 Clone sequences: six bases (a KpnI site) were missing from our predicted sequences for pDestTol2pA, pDestTol2pA2, pDestTol2CG, and pDestTol2CG2. Maps and sequences have all been corrected.
6/5/07 Sample results: Added images of sample results using IRES constructs.
5/11/07 Links: note that Invitrogen has issued a new version of the multisite Gateway manual, version D dated 3/7/07, which includes use of the new LR Clonase II Plus enzyme.
5/1/07 Main page: Moved revision history here from clone list page.
4/18/07 Sidebar: Added links for quick navigation.
4/17/07 Clone list: Added sequences for pDestTol2pA and pDestTol2CG (obsolete destination vectors).
3/23/07 Clone list: Sequences and maps now uploaded for all constructs.
2/20/07 Clone list: Sizes in bp have been added for all constructs.
