Dear Sir,
I am conducting research at the University of Louisiana,USA, infecting medaka with Mycobacterium marinum. I am concerned with the mode of infection and possible implications of chronic inflammation brought about by the infection. At the current time, I am planning to do TEM on infected fish. I am trying to figure out which fixative to use for TEM. Does someone have any advice in the right direction?

2003 European Zebrafish/Medaka Conference

Dear Colleagues,
The organizers of the 2003 European Zebrafish/Medaka Conference invite all scientists interested in fish development and genetics to discuss their results and ideas at the first fish meeting to be held in France, in Paris (June 11-14). Although this is a European meeting, scientists from non- European countries are encouragedto apply. We are looking forward to seeing you in Paris !
