Antibodies to Fish snRNPs

I have an undergraduate student who has initiated a project to look at the
developmental regulation of snRNP proteins in fish. She has been
successful at identifying snRNP proteins from mouse kidney, heart, brain,
and liver extracts by immunoblotting using the mouse monoclonal Y-12
antibody. However, when she carried out the same technique using fish
extracts, she was not able to obtain any antibody binding. She did a
control with mouse extracts at the same time and received positive
results. I have heard that the Y-12 mouse monoclonal does have a lowered
binding efficiency for non-mammalian snRNP proteins, but I didn't realize
that in some cases there would be no binding. I guess that epitope is not
very well conserved.
Has anyone used the Y12 antibody successfully with non-mammalian samples?
If you have, what conditions did you find to work well? Does anyone have
antibodies (mono- or polyclonal) that recognize fish snRNP proteins that
you would be willing to make available?
Thanks for your help,
You can respond directly to me.
