Discussing zebrafish genetic methods

This blog was originally set up to help plan a workshop held at the 2007 SCZI. During this workshop, it was clear that while there are some powerful new advances in genetic methods for the zebrafish, there are important questions about some existing methods, and several methods (notably homologous recombination and RNAi) which would be great for the field, but do not yet exist.

We've left this blog up as a forum in which people can discuss some of these methods. Below are several blog entries describing particular methods. Please add questions and comments under the appropriate heading.

Transient expression methods

There have been published results showing in vivo electroporation, lipofection, and viral infection in zebrafish embryos; the electroporation methods seem likely to be the most generally applicable. Jon Clarke and Steve Wilson's labs have shown very nice results with single-cell in vivo electroporation.

Global heat-shock of embryos and larvae is becoming very widely used as a method for expressing gene products at particular times (for instance to do late rescue of a mutant).

The Chien lab has also developed a very low-tech, reliable method for local heat-shock induction (using local heating with a modified soldering iron rather than sublethal laser illumination). A manuscript is in preparation; if you email Chi-Bin after about 1 March, we should be able to send you a draft.

I would be very intersted in hearing about the local heat shock method and any other tips/pitfalls of about using the heat shock system.

Hi there, it would be useful to know who left the comment rather than just "anonymous". Thanks!

I would also be interested in hearing about the local heat shock method

I would also be very interested hearing about this technique

Good words.
