I have the same problem too working with a Mab directed against
a surface antigen of oligodendrocytes.
I suppose that your epitope is conformation dependent; so I suggest 
the following: extract your material with 1 or 2% CHAPS containing
 0.5 M NaCl and try a dot blotting research .You will already see if
 there is some immunoreaction; If it is positive my assumption is 
probably correct. After that you may perhaps try an affinity column
with this extract and it will probably work!!!
Let me know your results
