“We” are trying an experiment to see if we can successfully preserve Zebrafish (Danio rerio) in 70% Ethanol (EtOH). I am saying “we” because I consulted Rich several times over the phone throughout the experiment. So far, the newly dead FLK1:GFP specimens (who carried out their entire lives in service to exhibits at the Exploratorium) are looking pretty official in their new specimen jars. The reason this is an experiment is because usually specimens are “fixed” in formalin before they’re transferred to EtOH for long-term storage–we skipped that step, to see if avoiding carcinogens like formalin is possible. I documented the process with our consumer-grade point-and-shoot camera (so please excuse the snap-shoddy photography).
