[Histonet] Effect of formamide solutions on proteins

I am not much of a chemist-type but if the proteins are not protected by
cross-linking with formaldehyde then using any solvent especially one a
potent as formamide can really reek havoc, especially on surface proteins,
sounds like a bad idea to me, without 24hr in formalin.

To all you chemist-types out there,

What effect might 50% formamide solutions have on lightly formalin-fixed
proteins? I know what affect is has on DNA, but what about other
structural proteins in the cell?
