Joe,

We have been using CD117 on FFPE sections for the past few years, using the
polyclonal antibodies from either Santa Cruz(C-19 cat# sc-168) or
Dako(A4502). The Dako Ab is absorbed against human. If you use the Santa
Cruz Ab be aware that you will have to add 10% heat inactivated human AB
serum to the diluent, to absorb. For more technical details see; Am. J.
Surg. Pathol. 23(4): 377-389, 1999.
