I think that giant hemoglobins of earthworms (at least up to 3.8 MD) will be
O.K. You can easily find a lot of references in Medline. I can remember that
somebody had passed the body fluid of earthworm through a gel filtration
column, collected the pink fraction,  and used it as a MW standard.
Unfortunately, I cannot remember the reference.
