constitutive promoters

[replab]

Hi,

I want to create stable transgenic zebrafish which have my gene 
being expressed behind a constitutive promoter. I would like to get 
expression throughout the entire embryo up until at least 7 days 
post fertilization. Does anyone have any suggestions on a good 
promoter  to use for this purpose? Any help is greatly appreciated.

much, Amy
