Hi everybody:

   I am brand new on the list, so I do not know if this question was posted
before. I apologize for this.
   I am trying to characterize a family of secreted proteins in the Nervous
System by immunohistochemistry, and with the regular fixation protocol that we
used (intracardiac perfusion with 4% PFA), I am not getting any good results.
Not even after some antigen-retrieval procedures. Before trying random things,
does anybody have a good protocol to get extracellular proteins well fixed? It
doesn't matter if it is set up for some other tissue, I would be glad to try
other protocol(s) if there are any available.
   Thank you very much for your help,
   Best regards,
   Diego.
