Geimsa colophonium stain?

[Peg Johnson]

Hello, 

I am trying to stain vegetative stages of a microsporidium in 
mosquito tissue embedded paraffin.  Currently, I am looking 
for a supplier of colophonium resin or Geimsa colophonium stain.

I could also use a protocol for staining 
paraffin sections with the Geimsa colophonium stain.

Any advice would be helpful...

Thanks in advance,
