[Histonet] Insulin Growth Factor-1 help

[Dana Settembre]

Hello,
I have been trying to get IGF-1 to work on formalin fixed paraffin
embedded human tissue and it's not working.
I am using Santa Cruz' IGF-1  rabbit polyclonal, (cat# sc-9013)
I have tried all sorts of retrievals and all sorts of dilutions with my
anti mouse/anti rabbit universal detection kit.
Things usually work one way or another and I am at my wits end.
Can someone who has gotten this antibody to work on FFPE human tissue
please let me know
what Vendor you use, retrieval, dilution, detection system?  
Thank you so much for any help.
