Virus immunolabeling

[Christine Pechoux]

Hi immunologists,

I use immunocytochemistry in electron microscopu to detect nucleocapsid
viral proteins. With my antibodies I detect an intracellular signal but
nothing inside the virus. I work on cryoultramicrotomy sections, normaly
high sensitive technique.
If you have had these kinds of problems and resolved them, I 'll very
happy to know your solutions.

      Thank you very much.
