Re: Can I keep the fly's head in a freezer a month before isolate the pigments

I don't know anything in particular about fly eye pigments. We usual feeze all out proteins in liquid nitrogen and store them at -80 C. But who knows about any one compound inparticular. There is a web site where all sorts of fly info is cataloged...you could definitely find someone who definitely works with those comounds there... Or email someone on a paper in the field. All I know about these fly people is that they seem very helpful. A Medline search would turn up names and addresses of people in the fly eye pigment field. Let me know if you need help.
