Zebrafish


USA Commercial Drug Discovery Customers!
Are you interested in using Morpholinos in zebrafish, or in having another firm do your Morpholino injections for you? Zygogen offers flexible research and drug discovery licenses as well as contract research services. For-Profit Entities in the USA wishing to use Morpholinos in zebrafish are required to obtain a license from Zygogen (www.zygogen.com). For license or contract research information, please call: 404-523-7309 or email: info@zygogen.com.

A database of zebrafish Morpholinos is available at Zfin, the Zebrafish Information Network. Look for Morpholino in the pulldown menu.

The New England Zebrafish Husbandry Association (NEZHA) is a professional organization dedicated to promoting the improvement of husbandry standards for usage of the zebrafish (Danio rerio) in scientific research.

This miRNA protocol by Wigard Kloosterman describes using Morpholinos to knockdown miRNA and LNA to detect miRNA in the zebrafish.

Cerda GA, Thomas JE, Allende ML, Karlstrom RO, Palma V. Electroporation of DNA, RNA, and morpholinos into zebrafish embryos. Methods. 2006 Jul;39(3):207-11.

Mary Mullins of U. Penn. has posted at MBL a zebrafish microinjection through the chorion protocol for a lab course along with an intro for the Morpholino lab.

The Smith lab at the Gurdon Institute has posted results of their Morpholino screen in Xenopus tropicalis.

The Harland lab at Berkeley has posted a protocol for microinjecting Morpholinos into Xenopus tropicalis oocytes.


Chick
