Shark IgM ! Chicken IgM !

[tomasz.bobrzynski at uci.agh.edu.pl]

I am looking for IgM antibodies of cartilaginous fish and for avian IgM (from non-immunized animals). Does anybody have any idea were I could obtain such antibodies? How can I purify IgM (not IgY) from birds? not quite sure if I should use eggs or blood. I would be gratefull if anyone could point me a protocol.
Thanks a lot in advance,
Tomasz.
