[3dem] Recalcitrant viruses

[Eduardo Sanz-Garcia]

Hi all,

I am working with a virus that likes a lot the carbon and doesn't want 
to go to the holes.
Here are some pictures (the picture are not the best but it is possible 
to see the effect):

I have tried glow discharged and no glow discharged grids.
I have also tried different type of buffers, virus concentration, 
dialysis, and several applications of the virus in the grid.

Has anyone had a similar problem?
Does anyone have a solution for this problem?
Thank you very, very much
