histology - help with antibodies (Aug/11/2010 )

I would like to do some pancreatic histology. Does anyone know good antibodies for insulin? It would also be great if anyone could suggest antibodies for IL-17, RORgt and luciferase. And should I do paraffin sections or cryosections?

There are many anti-insulin commercial tests and numerous suppliers of anti-insulin abs...meridian, Fitzgerald, EMD, etc.
